S01E01

The Man Trap

Stardate 1531.1: The Enterprise arrives at planet M-113 for an annual colony resupply and physical checkup of its residents and finds Professor Crater and his wife Nancy who is an old girlfriend of McCoy's. Crater immediately objects to the intrusion and tries to convince Kirk that an examination is not necessary and that their only need are salt tablets. Unknown to the landing party, each of them is seeing Nancy differently. McCoy sees her as the same youthful woman of his past while Kirk sees a hansome but older woman. Still, crewman Darnell sees Nancy as a blonde woman he met in the past and follows her into the nearby wilderness. Interrupted by the screams of Nancy, Kirk and McCoy race to the scene and find Darnell dead with Nancy standing nearby. Crater claims that the crewman died from the poison of the borgia plant found in his mouth, but Kirk is suspicious and orders everyone beamed up to the ship while he conducts an investigation. Unknown to the Enterprise crew, Nancy Crater is actually the sole survivor of M-113's native inhabitants, all of whom had the power to assume the shape of other life forms and to hypnotise their prey before killing them. Needing salt to survive, the M-113 creature killed Nancy for her body salt over a year prior to the Enterprise's visit, but the professor decided not to kill the creature because it was the last of its kind. Eventually, after several crewmen are killed on the planet and aboard the ship, Kirk and Spock learn of the creature and begin plotting its capture, but since it can assume the identity of other life forms, detection of the creature is difficult. Kirk asks Professor Crater for his help, but before any information can be obtained from Crater the salt creature, while disguised as McCoy, kills Crater and flees. Kirk corners the creature in McCoy's cabin but is overpowered by its hypnotic effect. Spock rushes in and strikes the creature until he himself is thrown against the wall. The creature returns to its true appearance and, horrified by the revelation, McCoy kills the creature before it can kill Kirk.

Charlie X

Stardate 1533.6: The Enterprise makes a rendezvous with the S.S. Antares and picks up a 17 year old boy, Charlie Evans who is the only survivor of a colony expedition that crashed on the planet Thasus. Captain Ramart and his staff rave about the boy, but Kirk can't help but be puzzled when Ramart refuses luxury items and hurries back to the Antares. Charlie, without social skills of any measure, seems a bit strange and unrefined but states that he grew up alone with only the record tapes from the wreckage for company. Sometime later, Captain Ramart signals the Enterprise and tries to warn Kirk about something, but just then the Antares is destroyed. Kirk doesn't think much about Charlie's disinterested reaction to the deaths of his former friends, but Spock begins to suspect that there is more to the boy than they know. This is confirmed when Charlie makes a crewman disappear for laughing at him while in the gym. During this time, Charlie becomes infatuated with the first "girl" he saw after coming aboard the Enterprise, Yeoman Rand. Unable to control his desires, Charlie pesters Rand until she is forced to hurt him, first by rejecting the boy and then by slapping him while in her quarters. This, of course, causes Charlie to make her disappear as well. Now realizing the full extent of Charlie's powers and the danger he could pose to civilization, Kirk tries to alter the ship's course away from their next stop, Colony 5, but Charlie learns of his plans, seizes control of the Enterprise, and locks in a course for Colony 5. By this time the Thasians, noncorporeal beings who really raised Charlie and gave him his powers, discover that the boy is missing and intercept the Enterprise. Despite Charlie's pleas not to be taken away, the Thasians remove Charlie from the Enterprise and restore the crew back to normal.

Where No Man Has Gone Before

Stardate 1312.4: The Enterprise encounters a record-marker left behind by the S.S. Valiant years ago as it tried to go through an energy barrier at the rim of the galaxy. After reading the badly damaged tapes they learn that the captain of the Valiant became obsessed with information on human psionics just before he ordered the destruction of his vessel. Despite the mystery, the Enterprise continues on to the rim of the galaxy in its own effort to get through the barrier. Once there the same energy forces which turned the Valiant away damage the Enterprise's engines and cause a strange behavioral change in Kirk's close friend, Gary Mitchell, changes which begin to alarm the command officers, especially Spock who watches closely as Mitchell gains incredible extrasensory powers. As Mitchell's powers grow stronger he begins to feel less connected with humanity and more concerned with his god-like abilities. Soon, he begins to see humans as insignificant; things to be squashed like insects. Despite Kirk's reluctance, he and Spock manage to contain Mitchell long enough to get to Delta Vega, a mining planet, and transport him down to the surface. As repairs proceed with the Enterprise, Mitchell's powers grow beyond Kirk's abilities to control. By now, Dr. Dehner realizes that she too has been affected by the energy barrier and begins to gain powers similar to Mitchell's. Mitchell escapes with Dehner, but Kirk follows with a phaser rifle. When he finds them, Mitchell tries to kill Kirk with his powers. Dehner, now realizing how corrupt Mitchell has become, helps Kirk weaken Mitchell before she succumbs to his psionic powers. But before Mitchell can fully regain his strength Kirk creates a rockfall and entombs Mitchell, bringing the threat he represents to humanity to an end.

The Naked Time

Stardate 1704.2: The Enterprise arrives at planet Psi 2000 to pick up a Federation research party from a planet that is quickly disintegrating, but after beaming down to the research facility Spock and Lieutenant Tormolen find all the scientists have died from strange causes. One has been strangled, one sits frozen at his station, apparently without a care in the world, and another is discovered in the shower, fully clothed. After making recordings of the incident the two beam back to the Enterprise, but not before Tormolen is accidentally infected by a water-borne virus that is still alive in the research center. Soon, Tormolen becomes so depressed by what he has witnessed on Psi 2000 that he attempts suicide, only later do die after surgery is performed to repair the minor wound. In trying to stop Tormolen from taking his life Sulu and Riley become infected with the virus, and later while on the bridge Sulu decides that he needs some exercise and abandons his post. When Spock discovers what has happened Riley burst out into irrational speech patterns and is ordered to sickbay. In a short period of time the senior officers conclude that whatever was responsible for killing the scientists on Psi 2000 has come aboard the Enterprise and is now affecting the crew. The only certainty is that everyone infected exhibits some deeply hidden emotion which is unique to every individual. Riley fancies himself a decendant of Irish kings while Sulu becomes a rapier armed swashbuckler who chases crewmembers throught the corridors of the ship. Nurse Chapel declairs her love to Spock who himself can't keep from crying over his past inability to tell his mother that he loved her. Meanwhile, as McCoy frantically searches for the antidote to the virus Riley locks himself into the engine room and shuts down the engines. By the time Kirk and Scotty break throught the locked door, only a few minutes are left to restart the engines, a process that normally takes thirty minutes, and save the ship from spiraling into the atmoshpere of Psi 2000. Kirk, desperate for an alternative, remembers an intermix formula that has never been tried which mixes matter and anitmatter cold. Spock, after shaking off the affects of the virus, helps Scotty restart the engines and save the ship, and in the process they discover a method for travelling back into time.

The Enemy Within

Stardate 1672.1: The landing party is conducting a geological survey of planet Alpha 177 when Geology technician Fisher falls from an embankment and is beamed aboard the Enterprise to be treated for an injured hand. After a rough beam-in, Scotty notices magnetic ore covering Fisher when the technician materializes and tells him to have the uniform decontaminated. Kirk beams up next and is unknowingly split into two seperate entities, one kind but weak and indecisive, the other vicious and cruel. Before anyone can determine what has happened, the evil Kirk demands brandy from McCoy and later attacks Yeoman Rand. When an animal is beamed aboard in an identical fashion, Spock makes the connection and concludes that the same thing must have happened to Kirk during a transporter malfunction. With the transporter out, the remaining crewmembers on the planet are forced to wait for repairs, but the nights on Alpha 177 are unbearably cold with the temperature dropping to -70 degrees. Meanwhile, Spock and a weakened Kirk conduct a search of the engineering deck where they find the evil Kirk hiding. They manage to capture the evil Kirk and restrain him in sickbay where Spock formulates his theory that it is the evil half of Kirk where the strength of command resides and that without his negative side Kirk is losing his ability to make command decisions. Worse still, the split appears to be killing the evil Kirk, and neither side can survive without the other. Scotty makes uncertain repairs to the transporter, and the split animal is sent through to be rejoined only to die in the attempt. With time running out, Kirk is convinced by Spock that the animal died from the fright of being rejoined and not due to a transporter malfunction and goes throught the transporter with this evil side. He returnes alive and whole and immediately orders the landing party beamed up, frostbitten but okay.

Mudd's Women

Stardate 1329.1: The Enterprise is pursuing an unidentified vessel which is overloading its engines in an effort to avoid capture. It enters an asteroid field, and Kirk decides to extend the ship's deflector screen around the helpless cargo vessel until the crew can be beamed aboard. While doing so, three of the four lithium crystals which power the Enterprise burn out and force the ship to seek replacement crystals on Rigel XII. Meanwhile, Kirk convenes a hearing where the captain of the cargo ship, Harcort Fenton "Harry" Mudd, and his "cargo," three women on their way to marry settlers, are investigated for their actions. Mudd's illegal activities are discovered along with his long list of past offenses. Mudd's women are not charged with a crime, but unfortunately for them Kirk's only concern is his ship and the replacement crystals and not what will happen to the women. When the Enterprise approaches Rigel XII, Mudd makes an unauthorized transmission to the miners and arranges a deal in which the three women will be exchanged for the crystals and the dropping of all charges against him. After seeing the women the miners agree, but Kirk refuses to comply and holds out until his ship nears a point in which it must have the crystals to keep from spiraling into the atmosphere. When Kirk finally agrees the head miner, Ben Childress, becomes more interested with Eve than with the fate of the Enterprise and makes Kirk wait until his ship is on the last few hours of emergency power. Eve, who has by this time become critical of Mudd and his buying and selling of the women, runs away. When Childress brings her back to the camp he learns that the women have been "pumped up" by the illegal Venus drug which makes the women more beautiful. By this time, Magda and Ruth have already married the other miners which angers Childress who now sees Harry's con. Childress turns Harry over to Kirk and allows access to the lithium crystals. With Kirk's help, Childress learns that Eve can be beautiful without the crystals, someone to care for him instead of being a useless pretty face.

What Are Little Girls Made Of?

Stardate 2712.4: Christine Chapel is a passenger aboard the Enterprise as it travels to Exo III in search of her fiance, exobiologist Dr. Korby, whose last message was from this frozen planet where he had discovered an underground cavern. The landing party beams down to greet the doctor and almost immediately two crewmen die in the cavern. Irritated by Korby's disinterest in the deaths, Kirk tries to check in with the Enterprise but is instead relieved of his phaser and communicator and forced to listen to Korby's vision of an improved human civilization through the transfer of human souls into android bodies. Korby shows Kirk the machinery left behind by the Old Ones, machinery he uses to create a android duplicate of Kirk in order to impress the captain. During this creation process the human Kirk concentrates on insulting Spock, a thought pattern which is transfered to the android. When he sees that Kirk is anything but impressed, Korby uses the duplicate to take star map information from the Enterprise so that he can select the first world to populate with androids. Spock senses trouble when the android Kirk insults him. He then beams down to Exo III with a security team. Meanwhile, Kirk convinces Ruk, an ancient android left behind by the Old Ones, that Korby is infesting his world with inferior and illogical lifeforms. Ruk attacks Korby but is destroyed by phaser fire. The android Kirk is then destroyed by the android Andrea. Korby pursues Kirk who learns, after the doctor injures his hand, that Korby himself is mostly android, forced into transfering his soul into a machine after nearly freezing to death. Kirk criticizes Korby's ideal civilization, and after listening to his argument, Korby destroys himself and Andrea.

Miri

Stardate 2713.5: The Enterprise answers an old-style distress signal from an unknown planet and discovers a world that is virtually identical to Earth of the 1960's. Beaming down, the landing party finds a civilization populated only by children. After McCoy is attacked by a diseased humanoid, the landing party manages to corner and question a young female, Miri, and quickly learns that 300 years ago scientists attempted a life-prolongation project which instead created a virus that wiped out the adult population. The children, however, were altered in that their aging is slowed considerably until they reach puberty where the virus rapidly destroys their changing bodies. Soon thereafter, all members of the landing party contract the virus except for Spock who becomes a carrier. McCoy begins work on an antidote while Kirk tries to contact the other children, all of whom are afraid of adults after witnessing their violent behaviors when affected by the virus. Miri, however, becomes interested in Kirk and spends more time with him until she learns that Yeoman Rand has had an interest in the captain as well. She then helps Jahn steal the landing party's communicators and abduct Rand. When Kirk shows Miri that she too is contracting the disease she agrees to help him recover Rand and the communicators. Meanwhile, McCoy and Spock have developed what might be the antidote, but without the communicators to interact with the ship's computers they are unable to know if the antidote will cure or kill them. Frustrated, McCoy tests the antidote on himself and fortunately becomes the first of the landing party to be free of the disease. With the virus eliminated, the Enterprise leaves the planet in the hands of Federation truant officers who will help the inhabitants rebuild their civilization.

Dagger of the Mind

Stardate 2715.1: While transferring cargo to the Tantalus Penal Colony, one of the inmates beams aboard the Enterprise and manages to make his way to the bridge before being disabled by a nerve pinch from Spock. By the time the Enterprise returns to Tantalus, McCoy has run a few tests on their stowaway and urges Kirk to begin an investigation of the penal colony despite the reputation of its director, Dr. Tristan Adams. Kirk beams down with Dr. Helen Noel, a psychiatrist, to learn more about the colony's activities. Meanwhile, Spock and McCoy discover that their patient is Dr. Simon van Gelder who was, six months ago, a part of the staff at Tantalus. Eventually, Kirk and Noel learn about a device, the neural neutralizer, that Adams is using to brainwash his patients. While testing the device, Adams takes the controls and uses the pain of the neutralizer's beam to force Kirk into surrendering his phaser and communicator. Because of Dr. van Gelder's conditioning under the device, he is unable to fully explain what has been happening on Tantalus. Spock, therefore, decides to risk a mind meld with van Gelder in which he learns the entire truth. Meanwhile, on Tantalus, Dr. Noel escapes via air-conditioning duct from the room where she is held and finds the power room. After a brief struggle with a guard, she lowers the defensive shields which allows Spock to beam down with a security detail. Kirk, who had been under the neutralizer's beam when the power died, is able to fight and get away from Adams who is left on the floor of the treatment room. When Spock restores power the neutralizer engages and drains the mind of Adams who dies from loneliness while under the beam. Dr. van Gelder is returned to Tantalus as the director of treatment. He dismantles and destroys the neural neutralizer.

The Corbomite Maneuver

Stardate 1512.2: During a routine star-mapping assignment in an uncharted section of the galaxy, the Enterprise encounters a space bouy of unknown origin. At first the bouy blocks the ship's path, but when Kirk decides to maneuver around the bouy it charges the ship, forcing Kirk to destroy it with phasers. After consideration, Kirk decides to continue on in an effort to discover the intelligence behind the bouy. Soon the Enterprise is confronted by a gigantic alien vessel, the Fesarius, which promptly grabs the Enterprise with its tractor beam and scans its record banks. After a futile effort by Kirk to communicate with the alien ship, Balok, the commander of the Fesarius, decides that the Enterprise must be destroyed and gives the crew 10 minutes to prepare. Lt. Bailey, a young and inexperienced bridge navigator, cracks under the pressure and is relieved from duty. With only a few minutes to spare, Kirk tries to bluff Balok, telling him that Earth ships are equipped with a corbomite device which, when touched with destructive energy, has the power to destroy the attacking vessel. Balok balks and decides instead to tow the Enterprise with a small pilot ship to an area where the crew will disembark and the vessel can be destroyed. While being towed, the bridge crew monitor Balok's ship, hoping he will grow careless. After Balok pulls ahead a bit and lowers his power levels, the Enterprise breaks Balok's tractor beam. Balok sends a distress call to the Fesarius, but it is too weak to be heard. Despite the danger, Kirk, McCoy, and Bailey beam over to the pilot ship and discover that the Fesarius is manned by one small and very friendly alien who has been testing the crew of the Enterprise to discover their real intentions. After deciding that an exchange of information would benefit both cultures, Bailey volunteers to stay behind as the first envoy to the First Federation.

The Menagerie (1)

Stardate 3012.4: The Enterprise arrives at Starbase 11, as ordered, but Kirk discovers that no such orders were issued. The ship's computers are checked despite the fact that Spock was the only person to actually see the transmission. While waiting, Kirk, Spock, and McCoy visit the former commander of the Enterprise, Fleet Captain Christopher Robin Pike, who has been paralyzed and disfigured by delta rays during a starship accident. After Spock is allowed to remain alone with his former captain, he reveals sketchy details of a plan to take the Enterprise on a mission of his own design, knowing full well that his actions will be considered mutiny. Pike objects, but Spock disobeys Pike and, with the help of the starbase computer facilities, sends bogus orders to the Enterprise. Spock beams up with Pike and immediately warps out of orbit on a course for Talos IV, a planet no one is allowed to visit under penalty of death. Kirk and Commodore Mendez pursue the Enterprise in a starbase shuttlecraft, and when Spock discovers that the occupants of the shuttle have already passed the point of safe return to Starbase 11 he locks the ship's computers on course, allows the shuttle to dock, and presents himself for arrest. Because there are now 3 officers of command rank on board, Spock demands an immediate court-martial. For his defense Spock presents scenes from an Enterprise voyage 13 years ago where under the command of Pike the Enterprise responded to a distress signal and visited Talos IV where they discovered crash survivors of a failed expedition. Among the survivors is Vena, a young woman who immediately attracts the attention of Pike. The crash site and the elderly scientists, however, are only an illusion placed in their minds by the Talosians. Pike is captured in the hopes that he and Vena will breed and repopulate the barren planet. Suddenly, the film ends abruptly. Mendez demands that the Enterprise be released to manual control, but Spock refuses to comply even though he knows that his life and Kirk's career both are at stake!

The Menagerie (2)

Stardate 3013.1: Despite Mendez, the court-martial continues, and the images begin to reappear on the breifing room screen. Captain Pike rejects Vena despite all the efforts of the Talosians to make her irresitable. To counter his resistance, the Talosians kidnap Number One and Yeoman Colt from the Enterprise so that Pike will have a choice of female partners. Meanwhile, Pike discovers that strong emotions can block the Talosians from reading his mind. He and the others manage to escape to the surface of the planet, but when the Talosians reveal that this was all a part of their plan, Number One threatens to detonate a hand laser, killing them all, unless they are released. After scanning the record banks of the Enterprise, the Talosians discover that humans have a unique hatred of captivity, a trait which would make humans too violent a species for their purposes. The Talosains free all of the humans, but Vena cannot join the Enterprise due to the injuries she sustained in the crash and the need for the illusion of health which the Talosians provide. When the story ends, Commodore Mendez disappears. The Talosians then address Kirk from the view screen, admitting that Mendez was never really on board and that the illusion of a trial was necessary to prevent him from taking control of his ship before it reached Talos IV. Now that the Enterprise has arrived, the Talosians offer Captain Pike a life with them and an illusion of health to free him from the limitations of his body. Pike accepts, Starfleet Command suspends General Order #7 which prohibits contact with Talos IV, and the mutiny charges against Spock are dropped. Kirk watches the screen as Pike appears on the planet's surface with Vena, both happy with their illusions of health and beauty.

The Conscience of the King

Stardate 2817.6: The Enterprise arrives at Planet Q, summoned by Dr. Thomas Leighton who claims to have developed a new synthetic food. When Kirk beams down he discovers that Leighton's real intention was to inform the captain that a travelling theatrical troupe's lead actor, Anton Karidian, is actually Kodos the Executioner. Kodos, 22 years ago, was the governor of Tarsus IV when it was suddenly hit with a food shortage. In an effort to relieve the crisis, Kodos executed 50 percent of the population. In the aftermath, Kodos was thought to have died but no body was ever recovered. Irritated at Leighton's actions and satisfied that Kodos is dead, Kirk beams back to the ship and prepares to leave orbit. Then, when Leighton dies of mysterious circumstances, Kirk arranges for the troupe's transportation to abandon them and then takes them aboard the Enterprise so that he may study Karidian while taking them to Benecia Colony. Soon after, Lieutenant Riley is poisoned and nearly dies. Concerned by the captain's growing obsession with Karidian, Spock searches the computers for information and learns that Kirk, Riley, and the late Thomas Leighton were the last remaining witnesses to the atrocities of Kodos and that all other witnesses have been systematically murdered when the theatrical troupe was nearby. When Riley overhears McCoy's report and learns that Kodos, a.k.a. Anton Karidian, killed Riley's parents, he enters the ship's theater intent on killing Karidian. Kirk intervenes and arrests Karidian but then learns that it is Lenore, Karidian's daughter, who has been killing the witnesses. She takes a phaser from a security guard and threatens Kirk, but just as she fires Karidian steps in front of the captain and dies. Horrified from killing her own father, Lenore goes insane.

Balance of Terror

Stardate 1709.1: A wedding between two crewmembers is interrupted when an Earth outpost along the Romulan border is attacked by an unidentified vessel. Kirk orders battlestations and the Enterprise races towards the Romulan Neutral Zone, an area separating the two powers which was established by subspace radio over 100 years ago, just as another outpost is destroyed. Kirk continues to try and identify the attacker, but Lieutenant Stiles, whose ancestors fought in the Romulan War, believes there isn't much doubt as to their identity. Sulu manages to pick up a visual image of a fleeing vessel and is able to track it despite an invisibility screen. Deciding to remain cautious until he can learn more about the attacker, Kirk orders the helmsman to shadow the vessel as it makes its way back to the Neutral Zone. The Romulans notice the Enterprise on its scanners but cannot determine if it's an enemy ship or a sensor echo. After holding a tactical meeting, and with some prodding from Stiles and Spock, Kirk decides that he must attack to prevent the enemy vessel from returning to its base and reporting Federation strength. After pounding the Romulan vessel with phaser fire, the Romulan commander de-cloaks and fires its plasma energy weapon and the Enterprise narrowly avoids destruction. Kirk pursues further and forces the Romulan ship into another exchange. A nuclear weapon is detonated and temporarily disables the Enterprise. Thinking the human vessel at his mercy, the Romulan commander moves in for the kill but falls into a trap. Despite a phaser coolant leak, the Enterprise heavily damages the Romulan vessel. Unwilling to surrender, the Romulan commander destroys his own ship.

Shore Leave

Stardate 3025.3: When the Enterprise arrives at an uncharted planet with hopes of conducting shore leave, the initial scouting parties find no animal or insect life forms, but what they do find is a quiet and beautiful planet which appears perfect for their needs. Shore leave is cancelled, however, when McCoy sees a likeness of Alice in Wonderland follow a large white rabbit through a hedge and no explanation can be found for the sudden appearance of life forms. Sulu then finds a 20th-century firearm, Yeoman Barrows encounters Don Juan, and Lieutenant Rodriguez narrowly escapes from a Bengal tiger and a Japanese fighter aircraft which injures Specialist Teller. Kirk finds it hard to take McCoy seriously until he meets Finnegan, a practical joker at the academy, and an old girlfriend, Ruth. Spock manages to beam down to the planet just before the transporter becomes inoperative and informs Kirk that an energy field on the planet is draining power from the Enterprise. The two hypothesize that the thoughts of the landing party are being read and that objects are being manufactured based on their thought patterns. Kirk orders all personnel to meet at the beamdown point, but just as Kirk and Spock arrive, McCoy is killed by a mounted knight. Eventually, the caretaker of the planet appears and insists that his world is simply an amusement park and that nothing they have experienced is permanent. McCoy is revived by the sophisticated machinery below the planet's surface, and the caretaker invites the Enterprise crew to enjoy what his planet has to offer. Kirk accepts and wanders off with Ruth. Spock, meanwhile, insists that he has had all the shore leave that he cares for and retunes to the ship.

The Galileo Seven

Stardate 2821.5: The Enterprise is scheduled to rendezvous with a ship which will deliver medical supplies to a plague-ridden Hansen's Planet but passes the quasar Murasake 312 and, under Starfleet orders, stops to investigate. Spock, McCoy, Scott, and four specialists board the shuttlecraft Galileo and head into Murasake 312 for observation. Unexpectedly, the Galileo is pulled off course and crashes on the planet Taurus II in the center of the Murasake phenomenon. While Scott attempts repairs, Latimer and Gaetano scout the area and eventually encounter the inhabitants of Taurus II, very large and hostile anthropoids armed with equally large Folsom Point spears. Latimer is killed by one of the anthropoids which brings Spock and the others running. When Spock shows more interest in the weapon than the dead crewman, Boma begins to criticize Spock's methods of command. The crew retreat to the shuttlecraft only to discover that the anthropoids seem to be preparing for an attack. Despite objections from the others, Spock insists that it will only be necessary to frighten the anthropoids, not to kill them, and uses their phasers to accomplish the task. Meanwhile, the Enterprise is searching Taurus II for the shuttlecraft and its crew but is hampered by instrument ionization and a belligerent Commissioner Ferris who urges Kirk to call off the search and proceed to the rendezvous point. On Taurus II, Scott manages to repair the shuttle and uses as a fuel source the power that has been drained from the hand phasers. As the anthropoids close in, the Galileo lifts off and manages to achieve a shaky orbit, but by this time the Enterprise has been forced to abandon the search. Without the power to pull away from the planets gravity field and with communications still disrupted by continued ionization, Spock dumps and ignites the remaining fuel in order to give the Enterprise a visual signal. Seeing the flare against the image of Taurus II, Kirk responds quickly and manages to beam the shuttle crew aboard just as the Galileo disintegrates from its decaying orbit.

The Squire of Gothos

Stardate 2124.5: While on course towards Colony Beta VI to deliver supplies, the Enterprise encounters a lone planet in a region of space devoid of stars. Without the time to stop and investigate further, Kirk orders the planet logged for future exploration and to resume their original course. Suddenly, Kirk and Sulu are abducted from the bridge. Spock concludes that the two must be on the planet below, even though the planet's atmosphere and environment are lethal to most life forms without protection, and orders McCoy, DeSalle, and geophysicist Jaeger to beam down and conduct a search. The landing party enters what appears to be a castle and finds the captain and Sulu along with Trelane, a brash and impetuous being who, on McCoy's medical scanner, does not appear to exist. When he sees the landing party, Trelane invites everyone to stay on Gothos for awhile and to discuss his favorite subject; Earth's military history. Spock, meanwhile, manages to locate the landing party and beams everyone, except Trelane, back to the ship. Unwilling to let his guests leave, Trelane brings the bridge crew back down for a banquet. While Trelane dances with Yeoman Ross, Kirk and Spock notice that their host never stays very far away from a large mirror on the wall and conclude that the mirror might be his source of power. To test his theory, Kirk provokes Trelane into a duel and destroys the mechanism behind the mirror. The bridge crew beam back to the Enterprise, but once again Trelane prevents their escape and brings Kirk back to Gothos to face trial for his "treason." In order to have his ship released, Kirk offers himself as the prey for a royal hunt. Trelane accepts, and the hunt begins. But just as he is about to kill Kirk and invite all the others down to "play," two energy beings appear and put a stop to their child's fun, telling him it's time to come home now. After apologizing to Kirk, the beings disappear, along with Trelane, and Kirk is allowed to return to the ship.

Arena

Stardate 3045.6: While in orbit above an isolated Federation outpost on Cestus III, Kirk, Spock, McCoy, and a few tactical officers beam down for a visit but soon discover that the outpost has recently been destroyed. Outnumbered, the landing party must fight off a mortar barrage from alien troops while looking for survivors. The Enterprise, meanwhile, is attacked by the alien's vessel and is compelled to disengage. Kirk finds the outpost's arsenal and, with the help of a Starfleet mortar, manages to halt the alien ground attack and force the aliens to transport back to their vessel. The landing party beams back to the Enterprise which begins pursuing the alien ship. Kirk decides that the alien surprise attack cannot go unpunished and becomes determined to destroy the attackers. The chase becomes a test of engineering capabilities for both sides as each ship pushes the limits of their warp drives. Suddenly, both ships are subjected to scanning beams and then brought to a complete stop with tractor beams from a nearby solar system inhabited by an advanced raced called the Metrons. The Metrons, who dislike trespassers and the violent intents of both the humans and the Gorns that they pursue, decide that the incident shall be settled in a different fashion and transport Kirk and the Gorn captain to an uninhabited asteroid where they will fight to the death. The winner will be free to leave while the loser, along with his ship and crew, will be destroyed in the interests of peace. Kirk then gets his first look at the Gorn captain, a very intelligent but equally powerful, lizard-like creature. During the contest, Kirk narrowly escapes the Gorn's attempt to trap and kill him with a chiseled dagger, and manages to combine the asteroid's mineral resources into gunpowder which he uses in a canon-like weapon to wound the Gorn captain. When Kirk refuses to kill the Gorn, a Metron appears and states that Kirk surprised them by displaying mercy to an enemy that certainly would have killed him. Because Kirk spared his opponent, the Metron concedes that there may be some hope for Kirk's species after all and allows both captains to return to their vessels and vacate the area.

Tomorrow is Yesterday

Stardate 3113.2: After successfully pulling away from a black star, the Enterprise is caught in a time warp that sends it back to Earth during the middle of the 20th-century. While the ship attempts to recover from a low orbit, Omaha Air Base detects the Enterprise on its radar and sends an interceptor to investigate and force the ship down. In an effort to keep the plane away from the Enterprise Kirk holds it with a tractor beam, but the plane breaks up under the pressure, and Kirk is forced to beam the pilot, Captain John Christopher, aboard. After being told that he cannot be returned to Earth for fear of changing history, Christopher tries to escape but is apprehended before he can do so. Spock then discovers that Christopher must be returned to Earth because his absence will effect history. While discussing the matter, Christopher reveals that he activated the gun camera on his aircraft during the encounter, so Kirk and Sulu beam down to steal the footage but are caught in the act by a police sergeant who is then accidentally beamed up to the Enterprise after activating the emergency signal on one of the communicators. As they continue their search, the landing party trips a silent alarm which brings the base security to the photo lab in force. Sulu manages to escape with the stolen records, but Kirk is arrested and questioned by a police colonel. To get the captain back, Spock and Christopher beam down and surprise the police. Christopher tries to escape again but is detained by the ever vigilant Spock. To get back to their time, Spock and Scotty manage to duplicate the conditions of the time warp. The Enterprise goes slightly back in time as it approaches the sun and then forward in time as it uses a slingshot effect to pull away from the sun. Captain Christopher and the police sergeant are beamed back to Earth before the incident ever happened, and after a bit of risky engineering and maneuvering the Enterprise returns to the 23rd-century.

Court Martial

Stardate 2947.3: After suffering the effects of a severe ion storm, including the death of Records Officer Benjamin Finney, the Enterprise puts in for repairs at Starbase 11. Kirk gives Commodore Stone his sworn testimony regarding the incident which, unexplainably, does not agree with the log tapes of the Enterprise computer. A hearing is held to determine if a court-martial is in order, and at that hearing Stone urges Kirk to take a ground assignment and have the affair swept under the rug for the good of the service. Unwilling to admit to negligence, Kirk demands a trial and later learns that an ex-girlfriend, Lieutenant Shaw, will be in charge of the prosecution. Shaw, however, wants to help Kirk and recommends defense attorney Samuel T. Cogley who wastes no time in moving into Kirk's starbase quarters. The prosecution builds its case on Kirk vs. the Enterprise computer log which clearly shows Kirk jettisoning an ion pod that contained Finney before calling for red alert even though Kirk maintains that the red alert did, in fact, exist at the time. In addition, Shaw reveals to the court an incident several years ago where Kirk logged a mistake made by Finney and suggests that because Finney blamed Kirk for the blot on his service record, Kirk might have reciprocated the bad feelings and jettisoned the pod out of malice. Spock, meanwhile, tests the Enterprise computer by playing chess against what should be an unbeatable computer opponent, and after winning several games concludes that the programming has been altered. To illustrate his theory, the trial is moved to the Enterprise. After Spock presents his evidence, Cogley, to the surprise of the court, blurts out that Finney is not dead but in hiding somewhere on the ship. The bulk of the crew are beamed down to Starbase 11 so that Finney can be found. After masking out the heartbeats of the remaining occupants, Finney is discovered in engineering and eventually confesses to framing Kirk and sabotaging the Enterprise while in orbit above Starbase 11. Kirk manages to find the damage Finney caused and make repairs before the ship's orbit completely decays.

The Return of the Archons

Stardate 3156.2: The Enterprise arrives at Beta III to investigate the disappearance of the U.S.S. Archon which took place over 100 years ago. When Sulu's behavior dramatically changes after returning from an initial survey of the planet's culture, Kirk beams down with another landing party to investigate. They are met by a calm and courteous group of citizenry who suddenly change into a wild and violent mob at the beginning of what is known as Red Hour. The landing party seek cover in a nearby hotel but come under the suspicion of an older man who claims that the newcomers are not of the "body" and quickly summons the lawgivers to deal with them. Kirk, however, refuses to accompany the lawgivers and instead follows Reger, a native Betan who promises to protect the landing party from the will of Landru. Landru, Kirk learns, is the being who controls every aspect of a Betan society where all but a handful of people who resist are part of the collective conscious known as the body. Red Hour, it seems, is the only time that the citizens are allowed to be independent and vent their built-up emotions. Despite their attempt to hide, Landru imprisons the landing party until each of its members are brought into the body by the absorption chamber. Kirk and Spock are saved by another member of the resistance and are led to the hall where Landru resides. They discover that Landru is actually a computer which was programmed by the original Landru, a scientist who lived over 6000 years ago, to lead his people towards peaceful progress. The computer, however, was not programmed with Landru's wisdom and over the years has interpreted the original Landru's guidelines so rigidly that freedom and self-expression have been sacrificed for a controlled peace and harmony. Kirk argues that the computer, in it's attempt to carry out Landru's wishes, has harmed the society by not allowing freedom and individualistic expression. Landru cannot escape Kirk's argument and destroys itself leaving the Betans free to develop a more humanistic society.

Stardate 3141.9: In the area of space near Starbase 12, the Enterprise encounters what appears to be a derelict spacecraft of 20th-century Earth origin. After beaming on board, the landing party discovers human life forms and that the vessel is a "sleeper ship," designed to carry its occupants in suspended animation during interplanetary travel. While inspecting the vessel, now known as S.S. Botany Bay, one of the occupants is revived via computer control and is nursed back to health aboard the Enterprise. Curious but suspicious, he introduces himself as Khan and gives sketchy details about his starflight. After attending a social gathering and being grilled by Spock, Khan decides to take control of the Enterprise with the help of Lieutenant Marla McGivers, a historian aboard the ship who has had feelings for Khan ever since he was revived. By this time, Kirk and the other senior officers have discovered who Khan, known as Khan Noonian Singh, and his followers really are; a group of genetically engineered "supermen" who ruled part of the Earth during the Genetics Wars of the 1990's. Khan is restricted to his quarters but easily overpowers the guard stationed there and quickly seizes control of the Enterprise. Needing the crew to carry out his galactic ambitions, Khan tries to persuade them by killing the captain if they refuse. McGivers, unwilling to participate in Kirk's death, rescues Kirk and helps the crew take back the ship. In the hearing which follows, Kirk drops all charges against Khan and his followers and instead maroons them on Ceti Alpha V, an inhospitable but habitable planet. Given the choice of court-martial or accompanying them, McGivers chooses to resign from Starfleet and live out her life with Khan.

A Taste of Armageddon

Stardate 3192.1: Kirk is ordered to open diplomatic relations with Eminiar VII at all costs, but the Enterprise is warned away from the planet as it approaches. On board is Ambassador Robert Fox who has been sent to head the dialogue and to extend an invitation to Eminiar VII and its sister planet, Vendikar, to join the Federation. Kirk and Spock beam down with a landing party, but they are immediately reminded of the warning to stay away from Eminiar. After investigating further, the landing party discovers that Eminiar VII has been at war with Vendikar for 500 years. The war, however, is fought with computers which select targets, compute damage, and assign groups of people as casualties. The people who are "killed" by the computer's computations then voluntarily report to disintegration chambers. While in orbit above Eminiar VII, the Enterprise is "attacked" by Vendikar and is recorded as destroyed. As a result, the crewmembers are required to beam down and report to disintegration chambers. To ensure their cooperation, the landing party is held hostage. After learning of their situation, Ambassador Fox decides to beam down in hopes of negotiating for the landing party's release, but then Fox himself is taken prisoner and held along with the others. Kirk is allowed to contact his ship so that he can convince the crew to cooperate, but instead Kirk uses the opportunity to issue a General Order 24 to Scotty, requiring that the engineer destroy Eminiar VII if Kirk and the landing party are not released. Eventually, Kirk and Spock manage to escape and find the computer control room where Kirk destroys the war computers. Rather than face the destruction and horrors of real warfare, the leaders of Eminiar VII decide to accept Ambassador Fox's help and make peace with the people of Vendikar.

This Side of Paradise

Stardate 3417.3: The Enterprise arrives at Omicron Ceti III, hoping to find surviving colonists who have been exposed to deadly berthold rays for three years. Surprisingly, the colonists are not only alive but in perfect health. While McCoy tries to unravel the mystery, Kirk attempts to convince the colonist's leader, Elias Sandoval, that an evacuation of the planet is imperative. None of the colonists, however, want to leave despite their lack of accomplishments and the deadly effects of the berthold rays. One of the colonists, Leila Kalomi, had met Spock six years earlier and fell in love with him. Eager to keep him on Omicron Ceti, she exposes Spock to a plant that contains spores which cause feelings of peace and contentment. When the spores manage to break down Spock's emotional barriers, he suddenly finds happiness and falls in love with Leila. Soon, the spores infect all of the landing party, except Kirk, and are beamed up to the Enterprise where they quickly take hold of the entire crew and compel them to join the colonists on the planet. While alone on the Enterprise, Kirk is finally overpowered by the spores and prepares to leave the ship. But, just as he is about to beam down, the thought of leaving the ship causes a violent reaction which destroys the spores in his body. Armed with a theory and a large club, Kirk tricks Spock into beaming back aboard where he taunts the Vulcan into a fight which destroys the spores. They then use subsonic sound waves to provoke a mass brawl on the planet below. Sandoval, no longer influenced by the spores, realizes that the colonists have accomplished nothing in their three years on Omicron Ceti and agrees to leave with the Enterprise and relocate to a planet where the colony is free to make progress and grow.

The Devil in the Dark

Stardate 3196.1: The Enterprise is ordered to the mining colony on Janus VI to investigate the deaths of several miners caused by an unknown menace. Kirk, Spock, and a security team beam down to help in the search, but shortly after talking to Chief Engineer Vanderberg, another miner is killed and a reactor pump is stolen. Scotty juryrigs a replacement but predicts an eventual reactor failure which would cause a planetwide contamination. Now facing a race against time, Kirk and Spock join the search directly and with the aid of Spock's tricorder, manage to find a silicon based life form that can easily burrow through the the planet's interior. They wound the creature with a phaser blast, but it escapes. While remaining on the same mining level, Kirk and Spock are forced to take separate tunnels. At one point the creature attempts to collapse Kirk's tunnel, but the captain avoids the debris and stumbles upon a large deposit of round silicon objects, the same objects that had been found throughout the lower mining levels and had somewhat interested Spock just after their arrival to Janus VI. Suddenly, the creature appears. Kirk draws his phaser, but the creature doesn't attack. When Spock discovers what's happening, he hurries to join the captain. After observing the creature for a short time, Spock decides to make telepathic contact and learns that the creature is a Horta, an intelligent and peaceful entity which turned to attacking the miners after the miners broke into her hatchery and destroyed many of the silicon objects which were her eggs. McCoy treats the Horta's injury, the reactor pump is retrieved, and a deal is struck which would bring the hostilities to an end. The miners will continue their operations while the Hortas burrow their way to the planet's mineral deposits. As the Enterprise departs from Janus VI, the miners learn to live among the Hortas and look forward to becoming embarrassingly rich.

Stardate 3198.4: While negotiations quickly break down between the Federation and the Klingon Empire, the Enterprise is sent to Organia, a planet of primitive people strategically located between the two sides. Kirk and Spock beam down in an attempt to convince the peaceful Organians to accept Federation aid and protection against the Klingons. The Organians, however, show no interest in their offer and suggest that they go back to the Enterprise as soon as possible. Confused by their response, Kirk tries to explain the benefits of Federation aid while emphasizing the horrors of a Klingon occupation. As predicted, the Klingons invade, and the Enterprise is forced to withdraw and wait for the Federation fleet. To help them, the Organians disguise Kirk and Spock as an Organian and a Vulcan merchant, but it isn't long until the two Enterprise officers sabotage a Klingon ammunition depot in an effort to keep the occupation army off balance and to show the Organians how to resist the Klingons. Shocked by what has taken place, the Organians reveal the identities of Kirk and Spock and allow them to be captured, but while they await execution the Organians set them free. Bewildered by their behavior, Kirk decides to ignore the Organians and concentrate on creating havoc for the Klingons while they wait for help. Meanwhile, the Enterprise returns to Organia, now reinforced with the Federation fleet. As both sides gear-up for battle, the Organians decide that something must be done and quickly deactivate every weapon on both sides. Not the primitives that they appeared, the Organians are actually highly advanced beings of energy who abhor violence. Both sides are forced to sign a peace treaty, leaving the Klingon commander musing over the glory that could have been.

The Alternative Factor

Stardate 3087.6: While in orbit above a barren planet, a strange phenomenon causes the planet to "wink out" and attain zero gravity, a state of non-existence, the effects of which are felt throughout the galaxy. Starfleet evacuates the area around the center of the effect and orders the Enterprise to investigate, fearing that what they are experiencing may be a prelude to an invasion from an alternate universe. Kirk, Spock, and a security team beam down to the planet after discovering a life form on the previously uninhabited world. The being they discover is Lazarus, a chaotic almost deranged, man who claims that the effect is being caused by his arch enemy who he is pursuing in a time traveling machine. Upon investigation, most of the wild claims appear to be lies, and Kirk becomes frustrated by Lazaurs. Adding to the confusion, Lazarus begins alternating from rage to calm, frantic insanity to complete control, while a wound on his head disappears and reappears. Lazarus learns of the ship's dilithium crystals and tells the captain that he needs the crystals so that he can find his enemy. Kirk refuses, but Lazarus steals the crystals anyway and then disappears. Kirk beams down to find Lazarus and accidentally transports to an alternate universe where he discovers that Lazarus is, in fact, two identical beings. Lazarus-A is a madman from Kirk's universe while Lazarus-B is a rational man from an alternate, anti-matter universe who has been shifting back and forth between both universes, trading places with Lazarus-A. Both beings cannot coexist in the same universe or both universes will be destroyed, yet this is precisely what Lazarus-A is trying to accomplish. Kirk decides to help Lazarus-B trap Lazarus-A inside a corridor between the two universes where both will exist until time itself is at an end. The plan succeeds, and both universes are saved. Kirk, however, can't help but wonder about the sacrifice made by Lazarus-B and what it would be like to fight a madman forever.

The City on the Edge of Forever

Stardate 3134.0: While investigating a time disturbance above an uncharted planet, Sulu is rendered unconscious when his overloaded console bursts into flames. McCoy hurries to the bridge and administers a few drops of cordrazine which immediately stabilizes the helmsman's heart flutter. Suddenly, the Enterprise lurches and McCoy is accidentally injected with a large quantity of the drug. In his cordrazine induced frenzy, McCoy exits the bridge and manages to beam himself down to the planet below. After beaming down to find the doctor, Kirk and the landing party discover the object causing the time disturbances, the Guardian of Forever, which can show any point of time in galactic history. While watching Earth's history, McCoy leaps through the portal and as a result drastically changes history. The Enterprise suddenly vanishes, leaving the landing party stranded and speculating if even Earth itself still exists. With no other alternative, Kirk asks the Guardian to replay the history they were viewing when McCoy jumped through the portal. At the point just before McCoy went through, Kirk and Spock jump back into Earth's past, into 1930's New York. After nearly being arrested for stealing clothes, they manage to find shelter and in the process meet Edith Keeler, a social worker who runs the homeless shelter where they are staying. While they wait for McCoy to appear, Kirk becomes quite enamored with Keeler whose insight into the future of mankind is full of optimism and hope. Spock, meanwhile, is able to tap into the memory banks of his tricorder and finds that in order to set things right again Edith Keeler must die. If McCoy is allowed to save her life, Keeler will eventually start a pacifist movement which will delay the entry of the U.S. into WWII and give the Nazis enough time to develop the atomic bomb first and conquer the world. When McCoy is finally reunited with his friends Kirk prevents him from moving Keeler out of the way of an oncoming truck, and she dies. With their history restored Spock, McCoy, and a devastated Kirk return through the time portal and beam back to the Enterprise.

Operation -- Annihilate!

Stardate 3287.2: An unexplainable epidemic of mass insanity has destroyed a line of civilizations through a portion of the Federation. The Deneva system, where Kirk's brother and his family lives, appears to be the next likely victim. When the Enterprise arrives, Kirk and a landing party beam down only to encounter a hostile reception and to discover that Kirk's brother Peter is dead. Aboard the Enterprise, Peter's widow gives Kirk information about the alien creatures on Deneva, but she dies soon after leaving many unanswered questions. After beaming down to investigate further, Spock is attacked by a flying creature and is infected by the same madness as everyone else on Deneva. McCoy soon discovers that these flying, single-celled creatures are separate parts of a single entity and are the cause of the madness. Tentacles from the parasites grow around a victim's nervous system and inflict considerable pain while forcing the victim to obey the entity. Spock, barely able to control the pain, returns to duty. He beams down to the planet and manages to capture one of the parasites for analysis aboard the Enterprise. After many tests they discover that the parasite creatures are vulnerable to intensely bright light, but when Spock is subjected to the same light which destroyed the parasite he is blinded in the test. Soon after, McCoy realizes that only ultraviolet light is necessary to destroy the parasites, but this information comes too late for Spock. Kirk orders satellite flares positioned around the planet which are able to fully eradicate the parasites and free the Devevans from their control. Surprisingly, Spock's blindness turns out to be temporary. The brightness of the Vulcan sun caused the development of an inner eyelid which protects Vulcans from intense light. With his sight fully restored, Spock returns to his station on the bridge.

Stardate 3372.7: While on course for Altair VI, Kirk learns from his chief medical officer that Spock's behavior is becoming increasingly irrational. When Kirk questions his first officer, Spock insists that all he needs is rest on his home planet of Vulcan. Kirk tries to accommodate Spock, but when inauguration ceremonies on Altair VI are rescheduled, the trip to Vulcan is cancelled. Spock changes the ship's course to Vulcan, and when Kirk learns what has happened he orders a complete medical examination of his first officer. McCoy soon discovers that Spock must be taken to Vulcan as soon as possible or he will die. Because of ritual ceremonies in childhood, Vulcans are bound to their mates while still young and are drawn to a time of mating when they are an adult. The physiological pressures are too strong to ignore, and if they aren't relieved they will prove fatal. Kirk disobeys direct orders and heads for Vulcan. Once there, Kirk, Spock, and McCoy beam down for the ceremony during which Spock's chosen mate, T'Pring, announces that she does not wish to be Spock's consort and invokes the Vulcan right of challenge. Spock must fight for her, but T'Pring selects Kirk as her champion instead of Stonn, a Vulcan male that T'Pring wants but will not risk by making him her champion. Kirk accepts the challenge, thinking that Spock is too weak to fight a healthy Vulcan, but he is unaware that the fight is to the death! During the fight McCoy is allowed to give Kirk a better chance by injecting him with a tri-ox compound, but Spock is too strong and chokes the captain to death. While McCoy takes the body back to the Enterprise, Spock feels his mating urge has vanished. He surrenders T'Pring to Stonn and returns to the ship. Once aboard he finds that Kirk is not dead after all. Instead of a tri-ox compound, McCoy slipped in a neural neutralizer which simulated death. Pleased at seeing his captain alive, Spock experiences a brief period of jubilation before returning to his normal, logical self.

Who Mourns for Adonais?

Stardate 3468.1: While entering orbit around Pollux IV, the Enterprise encounters an energy field in the shape of a giant green hand which holds the Enterprise in place. After trying to break free, an image of a head appears on the view screen and invites a landing party, excluding Spock, down to the planet. Once there, Kirk and the others meet a being who identifies himself as the god Apollo and refuses to allow the landing party to leave. He demands worship and plans to settle the crew of the Enterprise on Pollux IV and into a pastoral existence. Meanwhile, the archaeology and anthropology officer, Lt. Palamas, falls in love with Apollo, and Apollo makes plans for her to be his bride. Scott finds this offensive, but Apollo is too powerful and easily disposes of the engineer's attacks. However, after putting Scott in his place, Apollo appears to become tired and fades away. Kirk works up a plan to deliberately anger Apollo in hopes that the landing party can overpower their captor while he is in a weakened condition, but Lt. Palamas intervenes and convinces Apollo to be lenient. Unwilling to see his crew become permanent residents of Pollux IV, Kirk orders Lt. Palamas to reject Apollo for the sake of her fellow humans, which she does. Meanwhile, aboard the Enterprise, Spock locates the source of Apollo's power and is able to punch a hole through the energy field and destroy the power source with phaser fire. With his power gone, Apollo realizes that there is no room for gods anymore and appeals to the other gods to take him away.

Stardate 3451.9: The Enterprise crew discovers that the Malurian system has been destroyed, and during their investigation the ship is attacked by a small spacecraft of enormous power. When Kirk identifies himself, the attack abruptly ends and communication is established with the unknown vessel which happens to be small enough to be beamed aboard the Enterprise. Kirk learns that the vessel is actually a probe named Nomad and that the attack on the Enterprise was discontinued after Nomad identified Kirk as "the Kirk," its creator. After consulting the ship's computers, Spock finds that the probe's origin is indeed Earth and that its creator, Jackson Roykirk, programmed it to seek out new life. Nomad, however, does not look like the picture in the ship's record banks. Spock uses the Vulcan mind meld technique and discovers that Nomad was damaged in a meteor collision and drifted in space until it met another probe, Tan Ru, which was originally programmed to gather and sterilize soil samples. Now combined into one machine, Nomad believes that its mission is to seek out and destroy imperfect life forms. Unwilling to remain idle, Nomad erases Uhura's memory trying to learn what music is and kills Scott when he tries to interfere. Nomad repairs Scott, but Kirk finds that he has a bigger problem after learning that Nomad is returning to its launch point, Earth, where it will find billions of imperfect life forms and sterilize them. Kirk gambles by telling Nomad that he is not "the Kirk" that created it. Since Nomad made a mistake in identification, Kirk convinces Nomad that it is imperfect and must be destroyed. While analyzing its mistake, Kirk has Nomad beamed out into space where it quickly destroys itself.

Stardate not given: Kirk and a small landing party are trying to negotiate with the Halkans for Federation rights to mine dilithium crystals on their planet, but the ultra-peaceful Halkans are very reluctant to allow a mining treaty. When an ion storm arrives Kirk decides to return to the Enterprise until the storm passes, but just as Scott beams up the landing party the transporter malfunctions, sending Kirk, Scott, McCoy, and Uhura into an alternate universe and aboard the Imperial Starship Enterprise. Fortunately for them, none of the I.S.S. Enterprise crew notice any difference in the returning landing party. However, they soon realizes that in this mirror universe the Federation has been replaced by a Galactic Empire which holds its position through the use of terror and force. Even though the Halkans are just as peaceful in this universe, Kirk has been ordered to annihilate them if they do not comply with the Empire's demands. The crew expects him to decimate the Halkans immediately, but Kirk hesitates and then gives the Halkans 12 hours to comply which arouses the suspicions of Spock-2. After leaving the bridge Kirk is confronted by an ambitious Chekov-2 who attempts to assassinate Kirk for failing to follow imperial procedure, but his attempt is foiled by one of Chekov-2's henchman who decides to switch sides at the last moment. Imperial Starfleet sends Spock-2 secret orders to kill Kirk and proceed against the Halkans, but Spock-2 decides to warn Kirk of his orders and force the captain into killing the Halkans. Meanwhile, aboard the U.S.S. Enterprise, Spock realizes that something is wrong and orders the mirror universe landing party into the brig until he can figure out what has happened. Aboard the Imperial Enterprise, Kirk and Scotty work out a plan to use the ship's power to create conditions necessary to beam back to their own universe. Kirk manages to avoid potential trouble; Marlena-2, an ambitious captain's woman who knows how to use Kirk-2's secret weapon, the Tantalus Field, and Security Officer Sulu-2 who attempts to assassinate Kirk and Spock-2 and become the ship's captain. Spock-2 finally figures out what's happening and after being persuaded to help the U.S.S. Enterprise crew get back to their own universe, he operates the transporter during the beaming process. As he leaves, Kirk tries to convince Spock-2 to replace Kirk-2 as captain of the I.S.S. Enterprise, to spare the Halkans, and to work towards a more logical and less wasteful society in his own universe.

Stardate 3715.0: Kirk and a landing party beam down to investigate Gamma Trianguli VI and to make contact with its natives. The planet seems like a paradise until they discover plants that shoot deadly needles, exploding rocks, and highly accurate lightning bolts. When they try to beam up, Scott informs them that something on the planet has crippled the Enterprise's power and has made the transporter useless. When they finally meet the natives they discover them to be peacefully naive but immortal humanoids who live in primitive conditions and rely on what vegetation they have for food. Their society is created for them by Vaal, a rock formation looking much like a serpent's head. Upon further investigation, Vaal is found to be a highly sophisticated and powerful underground computer which needs daily food offerings from the natives to survive. Finding the Enterprise people a threat to the stability of the culture it supports, Vaal begins to slowly pull the Enterprise from its orbit. In order to eliminate the landing party it tries to teach the natives to kill but with poor results. With only hours until the Enterprise is destroyed, Kirk rounds up all of the natives and prevents them from feeding Vaal. The machine taps its energy reserve, but Kirk counters by having the Enterprise fire its phasers at Vaal's force field. After Vaal dies the natives wonder how they will survive. Kirk, however, is convinced that the natives are better off without Vaal and are now free to develop a culture of their own.

The Doomsday Machine

Stardate 4202.9: The Enterprise arrives in system L374 only to find that most of the planets have been destroyed. The two inner planets are still intact, and as the Enterprise draws closer they pick up a ship's distress beacon coming from a crippled U.S.S. Constellation (NCC-1017). Kirk and a landing party beam over to the ship to investigate and find only its commander, Commodore Matt Decker, still aboard. The commodore is weakened and in a state of shock but he is able, with the help of the ship's log, to piece together what happened. A giant robot ship has wandered into the galaxy and is destroying planets in its path, digesting the debris for fuel. The Constellation, in Decker's attempt to stop the robot ship, was rendered a floating hulk. With the ship's systems failing, Decker beamed his crew down to the third planet which has since been destroyed. Kirk and Scott stay on board the Constellation to rig her for tow while the others beam back to the Enterprise. Once there, the doomsday machine returns and attacks the Enterprise, thereby cutting off communications with the Constellation. Decker rejects Spock's plan to retreat in order to warn Starfleet and assumes command of the Enterprise. He then orders the ship to attack the doomsday machine. The attack is unsuccessful, but Decker is unwilling to retreat. Kirk and Scott finally manage to get the Constellation's impulse engines working and help the Enterprise escape from the doomsday machine's tractor beam. When communications is reestablished, Kirk and Spock relieve Decker from command. Beaten but not defeated, Decker steals a shuttlecraft and kills himself while piloting it into the maw of the robot ship. Learning from Decker's idea, Kirk decides to do the same with the Constellation and has Scott rig a delay detonation device. Kirk is transported back to the Enterprise just as the Constellation detonates inside the robot ship and destroys the doomsday machine's power system.

Stardate 3018.2: Only one man from the landing party investigating Pyris VII beams back to the Enterprise, and just after materializing he falls to the floor and dies. But when his mouth opens a voice speaks which warns Kirk to leave Pyris VII. Unwilling to abandon his chief engineer and helmsman, Kirk beams down to the planet with Spock and McCoy and encounter numerous images and objects related to Halloween; three witches, fog, a dark castle, a black cat, and a skeleton equipped dungeon where they find themselves after being captured. Scott and Sulu soon appear but are more zombie-like than human and force their shipmates at phaser-point to meet with Korob, an alien with humanoid appearance who at first requests only that Kirk and his officers enjoy his hospitality. He then tries to bribe them into leaving Pyris VII without Scott and Sulu. When that doesn't work, Korob's partner, Sylvia, appears and begins implementing a more hostile approach to persuade Kirk, including the use of sympathetic magic to overheat the Enterprise. When Korob sees this he becomes concerned and reminds Sylvia of their mission, but Sylvia is overwhelmed by the sensations of her human body and rejects Korob. She then tries to seduce Kirk and secure his help for her desire to conquer other worlds. Kirk goes along with Sylvia, but she soon discovers that he is only using her to save his ship. Korob helps Kirk and the others escape from the prison, but Sylvia becomes a giant cat and kills Korob by pushing the dungeon door on top of him. Kirk uses Korob's wand to destroy the illusions of the castle, the fog, and everything else the aliens had created, including their human shapes. The landing party then see Korob and Sylvia in their true form, tiny, blue, bird-like alien beings. Without the power of the wand to support them, Sylvia quickly falls dead next to the body of Korob.

I, Mudd

Stardate 4513.3: An android named Norman has been masquerading as an Enterprise crewman until he decides to capture the ship and take it to an uncharted planet. There, the landing party finds Harry Mudd with hundreds of androids to serve him. Harry proclaims himself King Mudd the First and begins showing off the beautiful female androids surounding him. He also shows the landing party a android duplicate of his harping wife Stella, an android he had created so that he could turn her off whenever he wishes. Harry explains to Kirk that he accidentally found this planet, an outpost full of adroids created by Andromedan beings centuries ago. They accepted Mudd as their ruler and protected him to the point of not allowing him to leave the planet. He then sent Norman out to find other humans to care for so that they would let him go. The androids, however, have other plans and take control of the starship so that they can spread throughout the universe and take care of all humanity. The Enterprise officers are offered incentives to stay, including immortality to Uhura. Unwilling to stay, the landing party and Mudd devise a plan to escape, but Uhura tells the androids of the plot. Her treachery, though, is only a ploy to trick the androids into thinking that the humans consider escape impossible. But instead of escaping, the humans act totally irrational and manage to overload and short-circuit the androids with their illogic. The landing party beams back to the ship but leaves Harry Mudd in the care and custody of the androids, including 500 newly constructed Stellas, until Harry decides to change his ways.

Metamorphosis

Stardate 3219.4: Assistant Federation Commissioner Nancy Hedford had been assigned to stop a war on Epsilon Canaris III, but after contracting Sakuro's disease, she was being shuttled to the Enterprise for treatment when a powerful energy cloud pulls the shuttlecraft off course to Gamma Canaris N. After a brief investigation of the shuttle and their surroundings, Kirk and the others find a humanoid man on the planet who claims to have been marooned there several years ago. He invites them to his shelter where they eventually learn his identity; Zefram Cochrane, a native of Alpha Centauri who discovered the space warp which helped pioneer faster than light travel. Cochrane, however, was thought to have died over 150 years ago. According to Cochrane, he journeyed out into space so that he could die there, but an entity he calls The Companion found him and rejuvinated his body, keeping him young and healthy. His body does not age; thus, he is immortal. Miss Hedford, however, is becoming increasingly sick and without proper medical treatment aboard the Enterprise she will die. Cochrane tells Kirk that the Companion brought them to the planet so that he would not be alone. But, after a discussion about current galactic exploration, Cochrane feels the urge to leave the planet and he decides to help Kirk in their escape. The plan doesn't work, so Kirk tries diplomacy and uses the universal translator to talk to The Companion. Surprisingly, they learn that The Companion has a female personality and is in love with Cochrane. Kirk tells The Companion that it cannot love Cochrane because it is not human. To better understand love, The Companion enters the dying body of Nancy Hedford, merging the two personalities into a single being. The result is a woman who appeals to Cochrane. Though he is now free to leave, Cochrane decides to stay on Gamma Canaris N with Nancy and live out the remainder of his now mortal life.

Journey to Babel

Stardate 3842.3: The Enterprise is transporting a group of ambassadors from various planets across the Federation to the Babel Conference. Among the representatives are Spock's parents, Vulcan Anbassador Sarek and his Terran wife Amanda. Spock and Sarek have not spoken to each other for 18 years, ever since Spock joined Starfleet instead of the Vulcan Science Academy. On Babel, many controversial issues will be discussed, including the admittance of dilithium-rich Coridan into the Federation. During a formal reception, Ambassador Gav, an argumentative Tellarite who opposes the admission of Coridan, quarrels with Sarek. Gav is later found murdered, and the circumstances of his death point to Sarek as being the killer. When Sarek is confronted he suddenly falls in pain from a recently discovered heart condition. McCoy must operate on Sarek soon or he will die. However, there is not enough T-negative blood on board. Spock suggests using an experimental drug which speeds up the producion of blood, but McCoy hesitates. Meanwhile, Kirk is attacked and seriously wounded by the Andorian Thelev. With Kirk unable to command the ship, Spock assumes command and, because of regulations, can no longer be the blood doner for the operation. When Kirk learns of this, he conceals the seriousness of his injury to Spock and reassumes command. McCoy begins the operation just as an unidentified vessel attacks the Enterprise. Kirk learns that the Andorian is actually and Orion sent to disrupt negotiations and keep Coridan from becoming a protected planet under the Federation. It was he who killed Ambassador Gav, not Sarek. Kirk manages to disable the attacking vessel, but it self-destructs and the Orion commits suicide. Sarek recovers and makes peace with his son as both realize a common bond. Kirk reports to sickbay, and McCoy finally gets the last word.

Friday's Child

Stardate 3497.2: The Enterprise travels to Capella IV in order to negotiate a mining treaty with the inhabitants, but when a landing party beams down they find that the Klingons have already arrived and have left a representative, named Kras, to secure a mining agreement for the Klingons. Kirk and Kras negotiate with Akaar, the leader of the tribes of Capella. Akaar favors the Federation while Maab, a highly influential Capellan, favors the Klingons. During a factional fight, Akaar is killed and Maab is installed as the new tribal leader. The landing party is imprisoned with Eleen, the pregnant widow of Akaar, and she prepares to be put to death according to custom. Kirk, however, finds a way to escape and brings Eleen with the landing party into the hills. While the Capellans search for the landing party, a Klingon warship attempts to keep the Enterprise from returning to Capella. In a cave McCoy delivers Eleen's son, but Eleen is still willing to give up her life and knocks McCoy unconscious. She returns to the Capellans claiming that the Federation men are dead. Kras, however, demands proof under the threat of a stolen phaser. Kirk shoots Kras in the leg with an arrow and as a result the Klingon threatens to kill anyone who raises a weapon against him. Maab, now seeing the Klingon for what he is, sacrifices himself so that one of his fellow warriors can kill Kras. The baby, named Leonard James Akaar, becomes the new tribal leader, and Eleen, the acting regent, signs the mining treaty.

The Deadly Years

Stardate 3478.2: The Enterprise arrives at Gamma Hydra IV to deliver supplies but finds the colony oddly quiet. When the landing party searches for survivors, Chekov discovers the body of a man who has apparently died of old age. The only colonists who are still alive are an elderly couple who claim to be in their late twenties. When the landing party returns to the Enterprise they all begin to experience the effects of rapid aging, all except Chekov. Kirk decides to remain in orbit until an answer can be found, but Commodore Stocker, a passenger on his way to Starbase 10 to assume his new post, urges Kirk to proceed to the Starbase so that they can receive the best treatment. Because of the rapid aging, Kirk begins to show an increasing inability to command the ship. Stocker feels there is no other choice but to order a compentency hearing, and Kirk is relieved of command. Stocker then orders the Enterprise through the Romulan Neutral Zone in order to arrive at Starbase 10 as quickly as possible. The Romulans, however, are on guard against such a move and immediately attack. Meanwhile, McCoy and Spock discover that the disease is a result of radiation poisoning and that Chekov was not affected because of sudden surge of adrenaline through his body after discovering the dead body on Gamma Hydra IV. Dr. Wallace and Spock hurriedly prepare an adrenaline-based drug which Kirk decides to test on himself. The drug works, and Kirk quickly makes his way to the bridge in time to save the ship. Scott, McCoy and Spock are then treated and brought back to their proper ages.

Obsession

Stardate 3619.2: While confirming a rich supply of di-kronium on Argus X, Kirk notices a sickly sweet smell in the air and sends a security team to investigate. Soon after, two of the men are dead from causes that Kirk has seen before. Years ago, when Kirk served aboard the U.S.S. Farragut, a mysterious cloud creature killed half of the crew, including the captain, by draining the blood from their bodies, and now Kirk believes that this is the same creature. He beams down again, but this time with a larger security force led by Ensign Garrovick, the son of Kirk's former commanding officer on the Farragut. The Ensign sees the creature but is caught off guard and delays firing his phaser. Two more men die, and Kirk blames Garrovick for their deaths. Despite orders to deliver medical supplies to Theta VII, Kirk is determined to pursue and destroy the creature. At this point, Spock and McCoy grow concerned about Kirk's obsession with the creature's destruction and then learn that, just like Garrovick, the young Lt. Kirk froze and delayed firing at the cloud creature and blames himself for the deaths aboard the Farragut. When the cloud leaves Argus X the Enterprise follows, but the creature is capable of speeds greater than the ship and Kirk is forced to back off. But suddenly, the cloud turns and attacks and enters the ship through an impulse vent, killing three crewmen until encountering Spock and his bad-tasting green blood. Scotty uses reverse pressure in the vents and manages to force the cloud out of the Enterprise. The cloud heads for Tycho IV, and Spock's analysis indicates that it will reproduce there, possibly creating thousands of creatures like itself. When the Enterprise arrives, Kirk and Garrovick beam down with a bottle of blood plasma and an antimatter bomb. Before they realize it, the cloud takes the blood which forces Kirk and Garrovick to act as bait. When the cloud approaches, Kirk orders the bomb detonated just as they beam back to the ship. Spock employs his transporter skills to save the two men, and the cloud creature is presumed to be destroyed in the blast.

Wolf in The Fold

Stardate 3614.9: To further his recovery from a head injury, Scott is escorted down to the planet Argelius II where Kirk and McCoy help him to relax by visiting a cabaret. There, Scott becomes interested in a dancer, Kara, and leaves the club with her. The captain and doctor leave the club as well, but after hearing screams they rush into an alley where they find Kara dead and a dazed Scott holding a blood-stained dagger. Despite the evidence, Scott claims to have no memory of the incident. Because Scott's head injury was caused by a female, McCoy begins to wonder if Scott has developed a subconscious anger towards women. The local authority, Commissioner Hengist from Rigel IV, is convinced of Scott's guilt and wants to end the matter immediately. Kirk tells Jaris, the prefect of Argelius, that the computers on the Enterprise would be able to find the truth and manages to gain permission to beam down a specialist, Lieutenant Tracy, to run a psychotricorder scan on Scott. While running the scan Lt. Tracy is found stabbed to death with Scott holding the same bloody dagger. Jaris calls for his psionic wife, Sybo, in order to solve the mystery, but during the ceremony she too is killed and once again the only suspect is Scott. Kirk convinces Jaris to move the investigation to the Enterprise, and it is there while under the scrutiny of the ship's computers that Scott's claims of amnesia are verified. With further aid from the computers, Spock discovers that the real killer is Jack the Ripper who, in its real form, is actually a noncorporeal entity that feeds on the fear of its victims. The creature has been hiding in the body of Hengist, and after it is discovered it flees into the Enterprise computer banks. Spock counters by giving the computer an impossible math problem to solve, forcing the entity from the computer. To keep the crew from being terrified, McCoy tranquilizes everyone which forces the entity back into Hengist's drugged body. Kirk immediately has Hengist's body transported into space at maximum dispersal where the entity will eventually die of starvation.

The Trouble With Tribbles

Stardate 4523.3: The Enterprise receives a Priority One distress signal from Space Station K-7 and hurries to the area prepared for battle. Kirk, however, is irritated to learn that it was Nilz Baris, the Federation Undersecretary for Agriculture, who issued the alarm only to have the quadrotriticale grain in the station's storage compartments protected. The grain is needed for the Sherman's Planet project, a system inside the neutral zone claimed by both the Federation and the Klingon Empire. Under the terms of the Organian Peace Treaty, rights to each planet are awarded to whichever side can most efficiently develop the planet to the benefit of its social systems. Soon after the Enterprise arives a Klingon ship enters the area. The station manager, Mr. Lurry, must observe the terms of the treaty and allow the Klingons to take shore leave there, but Kirk allows only twelve Klingons at a time on the station. Predictably, a fight breaks out between the Enterprise personel and several Klingon warriors which forces Kirk to cancel shore leave for everyone. Meanwhile, Cyrano Jones, a small-time merchant trader, introduces tribbles to the station. The tribbles, small purring balls of fur, seem harmless enough, but because all they do is eat and multilpy they soon overpopulate the station and the Enterprise. When they discover the tribbles in the ship's food preparation facilities, Spock points out that the tribbles may also be in the grain compartments on K-7 and immediately beams over with Kirk to investigate. The grain compartments, of course, are now filled with gorged tribbles, some of which are dead. McCoy finds that the grain has been poisoned, and with the help of tribbles that don't like Klingons, Baris' assistant is discovered to be a Klingon agent who confesses to poisoning the grain. The Klingons leave the station, and Jones is given the task of picking up every tribble on K-7. Scotty, meanwhile, rids the Enterprise of every tribble by beaming them into the engine room of the departing Klingon ship where, as Scotty puts it, "they'll be no tribble at all."

The Gamesters of Triskelion

Stardate 3211.7: Just before an inspection of automated installations on uninhabited Gamma II, Kirk, Chekov, and Uhura are beamed off of the bridge of the Enterprise. They find themselves on a strange planet in an entirely different solar system where they are immediately confronted by various aliens and forced to surrender. Confused and annoyed by their situation, Kirk demands an explanation but is informed only that they are on the planet Triskelion and that they are to spend the rest of their lives as gladiator thralls. Meanwhile, Spock discovers a particle trail that leads away from Gamma II and concludes that the landing party must be at the end of this trail. McCoy and Scotty object, but Spock is convinced and directs the Enterprise to follow the trail. On Triskelion, the landing party attempt an escape, but Galt, the Master Thrall, quickly subdues them by inflicting tremendous pain from the collars around their necks. Kirk then tries a diplomatic strategy and learns from his training instructor, a humanoid female named Shahna, that the Providers are responsible for their capture and that gambling on thrall combat is their primary occupation. Eventually, the Enterprise arrives at Triskelion, but the Providers plan to use its crew as thralls. Kirk manages to gain permission to see the Providers and then challenges them to the ultimate wager. Kirk will fight three thralls, and if he wins the thralls go free and will be educated by the Providers. However, if he loses the Enterprise crew will become thralls and give the Providers untold years of amusement. Shahna and the thralls fight fiercely, but Kirk wins the duel. In defeat, the Providers keep to their word and free the Enterprise and the thralls. They also agree to train the thralls and help them develop into a self-governing civilization.

A Piece of the Action

Stardate 4598.0: Over 100 years ago, before the Federation directive of non-interference, the U.S.S. Horizon visited the planet Iotia and reported its inhabitants as being extremely bright and imitative humanoids. Unfortunately, the Horizon accidentally left some materials behind, and the Enterprise has been ordered to investigate Iotia and learn what effect these items have had on the culture. Kirk, Spock and McCoy beam down to visit Bela Oxmyx, one of the planet's leaders, and discover a culture resembling America in the early 20th Century. They are escorted to Bela's office and further learn that the contamination comes from a book titled "Chicago Mobs of the Twenties." Bela tries to cut a deal with Kirk, offering a percentage of the profits he'll get from taking over the planet in exchange for the use of modern Federation weapons. Kirk refuses to cooperate and is detained until he decides to help Oxmyx. When the landing party escapes, Kirk orders Spock and McCoy back to the ship while he tries to clean up the mess made by the Federation. Unfortunately, Kirk is captured by a rival faction led by Jojo Krako who offers Kirk the same deal Oxmyx offered. But once again, Kirk refuses and is "put on ice" until he cooperates. While Kirk works on escape, Spock and McCoy are lured down to the planet again by Oxmyx. Kirk manages to get back to Oxmyx's office and decides on a different course of action. In order to unite the planet, he becomes a slang-talking "boss" himself to convince the Iotians that his "outfit," the Federation, is tougher than they are, and to prove it they're taking over the planet themselves. Kirk forces Oxmyx to call all the other bosses and has Scotty beam them, one by one, to Bela's office. When the Iotians doubt the power of the Federation, Kirk has Scotty stun everyone involved in a shootout on the street below. In the end, Kirk manages to convince the Iotians to work together for the good of everyone. A planetwide government is established in terms that the Iotians can understand. When they return to the ship, Spock wonders how Kirk will explain to Starfleet that a ship will be sent each year to Iotia to collect the Federation's "cut," and McCoy is worried about the implications of leaving his communicator behind with the copycat Iotians.

The Immunity Syndrome

Stardate 4307.1: After a long and tiring patrol the Enterprise crew are due for shore leave, but a priority message from Starfleet ends all of that with orders to assist in a rescue operation. All contact has been lost with solar system Gamma 7A, and the Enterprise is ordered to investigate. As the ship heads toward that region of space, Spock suffers a severe mind jolt and insists that the starship Intrepid (NCC-1631), manned exclusively by Vulcans, has been destroyed. The Enterprise moves closer and discovers only a zone of darkness in an area once populated by an entire star system. Kirk decides to enter the zone to investigate. While inside, Scotty reports a power drain from engineering, and McCoy informs the captain that the entire crew is suffering from a unexplained life-draining phenomenon. Without the power to leave the zone of darkness, the ship continues to advance and soon discovers a giant spacegoing amoeba that uses planetary systems as sources of food and energy. Spock takes a shuttlecraft closer to the amoeba in order to investigate and attempt to find the amoeba's weak spot. He discovers that the amoeba is ready to reproduce, and everyone realizes the danger that this emplies. Kirk orders the ship closer in an effort to plant an anti-matter bomb at its nucleus. After planting the bomb, the Enterprise tries to move away. Spock's shuttlecraft is detected, and Kirk orders a tractor beam locked onto the small vessel. Energy levels, though, are falling too fast, and the ship runs out of power just as the bomb detonates. Luckily, the Enterprise and Spock's shuttlecraft escape just in time.

A Private Little War

Stardate 4211.4: Spock and McCoy beam down to a planet that Kirk surveyed 13 years ago. At that time the natives were primitive but peaceful. On this visit, however, he is shocked to learn that the village natives have developed flintlock firearms and are engaged in a war against the hill people. When the landing party is discovered, Spock is wounded and hurriedly beamed back to the Enterprise. Kirk returns to the planet with McCoy in an effort to contact the captain's old friend, Tyree, who is now the leader of the hill people. But just after their arrival, Kirk is attacked and bitten by a Mugato. McCoy finds the hill people and has Kirk taken to their camp. Nona, a Kahn-ut-tu witch doctor and Tyree's wife, is able to save Kirk's life during a healing ceremony. After a quick look inside the village, Kirk and McCoy discover that the Klingons are giving the villagers the flintlocks so that they can kill the hill people more effectively. Nona, seeing that the Enterprise officers have the means to give the hill people superior weapons, becomes angry when Kirk refuses to help in that manner. Instead, the captain believes that stability can be achieved if they arm the hill people with the same type of weapons that the Klingons give the villagers. His reasoning is that a balance of power is the only way to preserve both sides. Nona's ambition causes her to steal a phaser and give it to the villagers. The villagers, however, distrust her motives and kill her. Though she was greedy and lusting for power, Tyree loved her, and her death finally motivates him to fight. When Kirk contacts the ship McCoy learns that Spock survived the surgery and is healthy, much to the doctor's surprise. Tired and ready to leave, they both beam back to the ship.

Stardate 4768.3: When the Enterprise visits a long dead planet, a voice calls out to Kirk from deep under the planet's surface asking for assistance. The senior officers are skeptical of Sargon's intentions, but Kirk decides to help and beams down to investigate. The landing party finds three living, highly intelligent, but disembodied entities living inside globes. They are Sargon, his wife Thalassa, and his former enemy Henoch. The remainder of their race has died, and Sargon no longer sees his differences with Henoch to be of any importance. Sargon wants to build android bodies that will contain their intelligence so that they can travel the galaxy and help others avoid the problems that led to their demise. But, in order to perform this task, they need the dexterity of human bodies to build the androids, and Sargon manages to convince Kirk to allow them to use the bodies of the captain, Spock, and Dr. Mulhall for short periods of time. After centuries of being disembodied, the aliens enjoy their brief experiences with human sensations. Henoch, however, decides that he wants to keep Spock's body and poisons Kirk/Sargon so that he will not interfere. But Sargon escapes, using powers that Henoch is unaware of, and Kirk's body is kept alive in sickbay until his mind can be returned to it from the globe. Sargon then destroys the globes and tricks Henoch into leaving Spock's body. Henoch dies, and Spock's consciousness, safely stored inside Nurse Chapel, returns to his own body. Now realizing the temptations of occupying human bodies and the unappealing nature of living inside an android, Sargon and Thalassa willingly abandon their work and accept oblivion and whatever awaits them.

Suddenly, the Enterprise is fired on with a nuclear missile, demonstrating technology that the Ekosians should not posses. Kirk and Spock beam down to investigate and find a society based on 20th Century Nazi Germany, complete with military uniforms, a fuhrer, and an ememy: the peaceful neighboring planet of Zeon. Kirk and Spock try to infiltrate the Nazi hierarchy but are captured in the attempt. With the help of the Zeon underground, the two manage to escape and learn that John Gill has violated the Prime Directive by becoming the Ekosian fuhrer. With the help of the underground, Kirk and Spock manage to get into Nazi headquarters to see John Gill but call on McCoy to help determine the historian's condition. McCoy discovers that Gill has been drugged and reluctantly gives him a stimulant so that Kirk can get some answers. Gill admits that he introduced Ekos to the order and discipline of Nazism in order to accelerate the development of their planet, but he had not counted on Melakon, the deputy fuhrer, seizing control and ordering the aggression against Zeon. With the help of more stimulants, Gill denounces Melakon and orders the cessation of hostilities but is immediately killed by Melakon who is then killed by a member of the Zeon underground. The Enterprise officers leave Ekos in the hands of those who plan to establish peaceful relations between the two planets and to reform Ekosian society.

Stardate 4657.5: Responding to a distress call from an Earth-like planet, a landing party from the Enterprise beams down to investigate. Soon, Kirk and the others learn that those responsible for the faked message are actually aliens from the Andromeda Galaxy sent out to scout for other galaxies to conquer. They managed to penetrate the energy barrier, but their ship was destroyed in the attempt. Now they need the Enterprise in their return trip to Andromeda, a voyage which will take 300 years and many generations of Kelvans to complete. The Kelvans are ruthless in their methods, planning to eventually return to this galaxy from Andromeda and conquer all other civilizations in their path. Kirk is unable to fight the paralysis field the Kelvans employ against them, and he seems willing to accept their fate. But once out of the galaxy, Kirk, Spock, McCoy, and Scotty, the only Enterprise crewmembers not reduced to crystalline form, discover a weakness in the Kelvan's plans. Because they were forced to take human form, the Kelvan's seem to show confusion over their newly acquired human senses and emotions. In order to save the ship, Kirk and the others work on giving the Kelvan's an overload to their senses. Scotty gets one of the Kelvans drunk while Kirk makes advances towards the Kelvan female, Kelinda, which makes the Kelvan leader, Rojan, extremely jealous. McCoy injects one of the other Kelvans with an irritant, claiming it to be vitamins, which causes him to be quarrelsome. A fight breaks out between Rojan and Kirk over Kelinda, and Kirk manages to convince Rojan that because of they're exposure to humans the Kelvan descendants that finally reach Andromeda will be so alien to other Kelvans that they will be considered invaders. Rojan accepts Kirk's offer of help from the Federation, and McCoy suggests that the planet they took refuge on would make a perfect place to begin their own colony.

Stardate not given: Upon approaching planet Omega IV, the Enterprise finds the missing starship Exeter (NCC-1672) in orbit but is unable to communicate with her. Kirk beams over with a landing party and finds all of the crew dead from a mysterious disease. After reviewing the chief surgeon's final log report which warns boarders not to carry the virus back to their ship, Kirk and the others hurriedly beam down to the planet. On Omega IV the landing party finds Captain Ron Tracey, commander of the Exeter, who has been living with a group of villagers called the Kohms since being stranded on the planet. But soon, Spock discovers that Tracey has also been violating the Prime Directive by killing hundreds of barbarian Yang raiders! Tracey takes the landing party captive and explains to Kirk that he believes Omega IV holds the secret to immortality and offers proof in the form of 1000 year old Kohn villagers. He then demands additional phasers from the Enterprise and forces McCoy to search for a longevity serum. But Kirk refuses to cooperate and is thrown into a cell with a Yang chieftain where he learns that Omega IV fought the devistating war that Earth avoided. McCoy eventually learns that exposure to the Omegan atmosphere kills the virus and that the inhabitants of Omega IV are long lived because they have evolved in that direction. Kirk and Tracey are forced to fight a duel to determine which side is good and which is evil. Kirk wins and, as the crew of The Enterprise arrive in time to save him and place Capt. Tracey under arrest, manages to convince the Yang leader, Cloud William, that the holy words and documents that they cherish must apply to everyone or they mean nothing. Cloud William does not fully understand but promises that the holy words will be obeyed.

The Ultimate Computer

Stardate 4729.4: Dr. Richard Daystrom has developed the next generation of computers, the M-5 Multitronic Unit, and Starfleet has ordered the device to be tested aboard the Enterprise. Once installed, tests begin with simple maneuvers and navigation problems, tasks which Kirk feel do not deserve the lavish attention given to the computer. After a mock engagement with the U.S.S. Lexington (NCC-1709) where the M-5 shows remarkable skill in defending the Enterprise, Commodore Wesley, the Lexington's commander, teases Kirk about being replaced by a computer. The performance of the M-5 pleases Daystrom, but at the same time Kirk feels uncomfortable about serving under a machine. The next test for the M-5 is an unexpected one in which the computer goes out of its way to destroy an ore freighter. Because of this unexplained behavior Kirk orders the M-5 deactivated, but the computer refuses to surrender control of he ship. A plan to cut off its power fails, and the bridge crew can only helplessly watch as the M-5 cripples a task force of four starships -- Hood (NCC-1703), Potemkin (NCC-1657), Excalibur (NCC-1664) and Lexington -- sent to further test the computer's capabilities. When one starship, Excalibur, is destroyed in the attack, Commodore Wesley is given the order to destroy the Enterprise in self-defense, and after Daystrom fails to convince his creation to stand down, Kirk uses the M-5's programmed sense of humanism to convince it that it has committed murder. The M-5 agrees and lowers the Enterprise shields so that the attacking force can easily destroy the Enterprise and thus itself. Kirk regains control but decides to gamble on Commodore Wesley's humanity and keep the shields lowered. Wesley calls off the attack, the M-5's plug is pulled, and Dr. Daystrom suffers an emotional breakdown.

Stardate 4040.7: The S.S. Beagle, missing for six years, is found as debris near Planet IV of System 982. Kirk, Spock, and McCoy beam down to the planet to investigate and find a ragged group of fugitive slaves trying to stay hidden from the police. These "sun worshippers" distrust the landing party but soon discover that they are not a threat. Kirk informs them that he is looking for another group of strangers led by a man named Merik. Merikus is the First Citizen of the Empire, but Kirk is not sure if it is the same man. Pursuaded to help them find Merik and his crew, the leader of the fugitives sends Flavius, an ex-gladiator, to be their guide. The landing party, however, is soon captured and led into the city where they discover a civilization much like 20th century Earth, but culturally similar to ancient Rome. The landing party find Merik, now First Citizen Merikus, who six years ago abandoned his ship and beamed his crew down to the planet. Those who could adapt survived, and those who couldn't died in the arena games. Kirk is ordered by Proconsul Claudius Marcus to have his crew beamed down. When Kirk refuses, Claudius tries to have Spock and McCoy killed in the games, but his plan fails. The next morning, Kirk is scheduled for execution, but Scotty manages to disrupt the planet's power systems which gives Kirk the opportunity to free Spock and McCoy. Now knowing that he made the wrong decision, Merik uses a communicator to signal the Enterprise and have the landing party beamed to the ship. For his treachery, Merik is killed by Claudius Marcus. On the Enterprise, Uhura clears up the confusion surrounding the religion of the runaway slaves. After listening to radio broadcasts from the planet, she has learned that the ex-slaves are actually Christians worshipping the "Son" of God and not the "sun" in the sky.

Assignment: Earth

Stardate not given: The Enterprise is sent on a mission back to Earth in the year 1968 to discover details about how the planet survived the arms race. While in orbit, the ship intercepts a transporter beam from an unknown part of the galaxy and beams the space traveler aboard. Surprised by what has taken place, the man identifies himself as Gary Seven and claims to be a 20th Century Earthman raised on an unknown world and trained to prevent Earth from destroying itself. Kirk decides to verify Seven's story before releasing him, but Seven escapes and beams down to the planet below. Kirk and Spock follow him to New York City, and Seven meanwhile discovers that two of his fellow agents have been killed in a auto accident. Seven is forced to complete their mission himself which is to sabotage an orbital nuclear platform, just low enough in the atmosphere to scare Earth leaders into prohibiting additional nuclear space weapons. Just as Kirk and Spock arrive, Seven beams out of his office and materializes at the rocket base where the nuclear platform is scheduled to launch. As he works on the rocket, Seven is almost beamed back to the Enterprise until his well intentioned secretary Roberta Lincoln accidentally pulls him back to his New York office.

Kirk finds that the monolith can be opened by the combination of sounds found in the order "Kirk to Enterprise," but when he enters the obelisk, he is attacked by waves of energy that erase his mind. With no time to spare, Spock and McCoy have to return to the Enterprise without Kirk, and begin trying to use the ship's tractor beam to divert the asteroid. Meanwhile, Kirk becomes the tribal chief, takes a wife and even expects to become a father, but the Enterprise may not be able to save her former captain's future.

Also beaming aboard is Larry Marvick, one of the original designers of the Enterprise - and hopelessly in love with Miranda, although she has chosen to spend her life serving as a liason between the Medusans and other humanoids.

For the World is Hollow and I Have Touched the Sky

Stardate 5476.3: McCoy tells Kirk that the most recent routine medical exams of the entire crew have revealed a case of a terminal but non-contagious disease. The victim is McCoy himself. Kirk recommends that the doctor resign immediately, but before the discussion gets any further, Kirk leads Spock and McCoy on a landing party mission to the asteroid-like vessel called Yonada, carefully disguised inside to make it appear to the humanoid inhabitants that they are on the surface of a planet. Kirk finds that the "world" is controlled by a computer known by the residents of Yonada as the Oracle, and the Oracle's instructions are being taken as a religious order. The high priestess catches McCoy's eye and asks him to remain with her - an offer which, considering the doctor's current state, McCoy finds tempting.

The Tholian Web

Stardate 5693.2: The Enterprise arrives at the last known position of the U.S.S. Defiant (NCC-1764), an area of uncharted space, to search for the missing starship. When the Defiant appears on the viewing screen enshrouded in a strange green glow, Spock is unable to scan the vessel on his sensors. Kirk beams over to the Defiant with a boarding party to investigate and finds the entire crew dead. What's more, the Defiant seems to be trapped in an interphase between two different universes. A power loss partially disables the Enterprise transporter, but the landing party manages to beam back to the Enterprise except Kirk who suddenly disappears along with the Defiant. Spock calculates that the next time to interphase will be approximately two hours, and that the captain can be rescued at that time. As the Enterprise begins to experience the same problems that doomed the Defiant: power loss, weakness and insanity among the crew, an alien vessel appears and demands that they leave Tholian territory or be destroyed. Spock explains that they are involved in rescue operations and requests that they stand by until the next interphase. The Tholians agree to wait, but when the next interphase occurs, the captain cannot be recovered due to the disturbance in space caused by the Tholian intrusion. The Tholian ship opens fire on the Enterprise, and when Spock returns fire the Enterprise manages to disable the Tholian vessel but at the cost of a further power loss and growing insanity among the crew. Another Tholian vessel appears, and together they begin construction on an energy web designed to capture the Enterprise. Spock declairs the captain dead and urges hurried repairs to the Enterprise before the Tholians complete their web. But once Kirk is seen by the bridge crew still trapped in interphase, Spock determines that they might still be able to recover him during the next interphase which will occur just as the Tholians will be completing the web. The Enterprise manages to disappear into interphase and reappear several parsecs from Tholian territory. Kirk is beamed aboard unharmed after being pulled to safety in the ship's transporter field.

The woman continues to appear, naming her victim on arrival and killing them by touch. Sulu is nearly killed by her, and the woman appears on the Enterprise as well, sabotaging the engines so the ship will never retrieve Kirk's survey team, stranding them - as well as the crew of the Enterprise - with an unpredictable murderer.

Stardate 5818.4: Beaming down to pick up a consignment of zenite from the planet Ardana, the home of Stratos, a city that floats above the surface of the planet, Kirk and Spock, who are there to pick up a consignment of zenite, are ambushed by mineworkers known as Troglytes. The attack is cut short by the arrival of Plasus, a high advisor from Stratos, who says that a disruptive group of protesting Troglytes probably stole the zenite shipment, which was missing. On Stratos, which Plasus says is safe, there is also evidence of Troglyte terrorism. Kirk and Spock discover that the Stratos dwellers live an easy life thanks to their planet's unique mineral resources at the expense of the Troglytes, who get no reward for extracting those resources. When McCoy finds that the raw zenite being mined by the Troglytes is having an adverse affect on their health, Kirk takes it upon himself to upset the balance in favor of equality.

The Savage Curtain

Stardate 5906.4: Over the planet Excalbia, the Enterprise is intercepted by who appears to be Abraham Lincoln, floating through space. Beaming aboard, Lincoln is welcomed by Kirk, who is somewhat awed by the presence of one of his most revered figures of history. "Lincoln" extends an invitation to Kirk and Spock to visit the planet, whose normally lava-covered surface sprouts a zone of Earthlike safety just for the landing party. Kirk, Spock and Lincoln are joined on the surface by an image of Surak, who initiated the doctrine of emotional restraint on Vulcan. A rock-creature appears and introduces Kirk and Spock to four more illusionary figures from history, this time the fiercest conquerors, tyrants and villains of the past, from Earth's Genghis Khan to Kahless the Unforgettable, who, as Surak did for Vulcan, set the standard of behavior for the Klingons. The creature pits the best and most noble - Kirk, Spock, Lincoln and Surak - against the most vile historical figures. The rewards for Kirk and Spock, should they survive, are their lives, and the lives of everyone aboard the Enterprise.

All Our Yesterdays

Stardate 5943.7: Arriving at the moon Sarpiedon, whose mother planet is due to explode in three hours, Kirk, Spock and McCoy find just what the ship's sensors indicated on the surface - no life forms, though an advanced civilization obviously once existed. But they then find several copies of Sarpiedon's librarian, Mr. Atoz. Some of the clones are helpful, others belligerent, but they all tell the landing party that all the people of Sarpiedon have already escaped to safety, and Atoz, thinking that Kirk and the others are natives who arrived late, advises them to do the same. The library turns out to be a file of "time periods" into which a device Atoz calls the atavachron can propel them, as it has already provided an escape for the rest of the moon's inhabitants. Hearing a woman screaming, but not realizing that she is one the other side of tha atavachron's time portal, Kirk leaps into a time period similar to the 1800s, and Spock and McCoy stumble into an ice age trying to retrieve him. All three must try to survive long enough in their respective environments for the time portal back to Sarpiedon to return - if that moon still exists in the 23rd century for them to return to.

Turnabout Intruder

Stardate 5298.5: Visiting Dr. Coleman and the ailing Dr. Lester, a colleague of Kirk's from Starfleet Academy who has always envied him due to her inability to achieve a captaincy in a male-captains-only Starfleet, Kirk is rendered unconscious by Lester. It turns out to have been a trap, and Lester puts herself and Kirk into an unknown device that transfers their minds into one another's bodies. Lester, in the form of Kirk, doesn't have time to kill Kirk (now in the female body). Lester and Coleman make every attempt to leave Kirk on the planet, but must bring "her" aboard to save face. Kirk, still suffering a severe shock from the mind transfer, is unable to warn McCoy about Lester's plan to command the Enterprise (especially when Lester keeps ordering Kirk sedated). Lester, however, is unable to conceal her lack of knowledge of command procedures and, more specifically, Kirk's character, and when Spock learns the truth and attempts to help Kirk, Lester has him placed under arrest and tries to speed Spock's court-martial toward a conclusion which would have Kirk and Spock executed.
