Poster for episode Rising (1).

Rising (1)

Several million years ago, the continent of Antarctica has become covered in ice. Their lies the great city of the Ancients, Atlantis -- but no longer. One Ancient bids a solemn farewell to another, who will stay behind. The great city lifts off the surface and flies away like a great ship, leaving behind only a small outpost and the woman, who scientists will discover frozen in the ice millions of years later, and name "Ayiana" ("Frozen").In the present day, an international expedition has been set up on the same site to study the outpost of the Ancients and the technology therein. It is headed by Dr. Elizabeth Weir, recently transferred from Stargate Command. Also present are Canadian astrophysicist Rodney McKay, Scottish medical doctor Carson Beckett, British scientist Peter Grodin, and many others. Dr. Daniel Jackson is also there, and eagerly reports his findings to Weir and McKay: He's found a Stargate address to the Ancients' lost city itself -- Atlantis -- which is now in the distant Pegasus Galaxy.Brigadier General Jack O'Neill heads toward the Antarctic base in a helicopter piloted by Major John Sheppard, who is stationed at the nearby McMurdo Air Force Base and who knows nothing about Ancients or Stargates. But when Dr. Beckett accidentally activates an Ancient drone weapon -- he possesses the rare gene that allows him to use the base's chair control mechanism -- Sheppard must take evasive action to keep from being shot down. The weapon is disabled in the nick of time, and Sheppard and O'Neill arrive safely (if not a bit cranky) at the outpost.Daniel explains his findings to the general, who does not approve an exploratory mission to the lost city when he learns that it will take their only Z.P.M. -- zero-point module, the Ancient power source that has enabled the outpost and saved Earth from the Goa'uld -- to dial a Stargate address beyond our galaxy. Weir and Jackson manage to convince him, though, based on the great wealth of Ancient technology (including more Z.P.M.s) that they are likely to find should they discover Atlantis intact.The mission is a go, and Weir's team of international scientists and military personnel -- which she has been assembling for months -- arrives at Stargate Command, deep inside Cheyenne Mountain. Daniel is disappointed that he cannot go with them, especially when a wormhole to Atlantis is successfully established. Dozens of men and women and tremendous amounts of equipment file through the gate, knowing that because of the massive power requirements they'll probably only get one shot at it. They are all volunteers, the best and brightest that Earth has to offer, who go knowing full well that they may never be able to return home.Even the reluctant Major Sheppard, after some convincing by O'Neill, has agreed to go. Weir wants him there, despite a black mark on his service record for disobeying orders to save the lives of fellow servicemen, because Sheppard too possesses the gene that allows him to use Ancient technology. While some, like Beckett, and learn to use it with concentration and training, for Sheppard it's easy and instinctive.The team is lead by military commander Colonel Marshall Sumner, who is the first to step through to Atlantis. The facility is cleared and secured, and remarkably the systems begin to activate and light up as the humans begin exploring the massive city. Two scientists find a bay filled with Ancient ships capable of travelling through the Stargate; Dr. McKay finds the control room with Stargate dialing controls; and it's not long before the team discovers that the entire city, protected by a massive energy shield, is underwater.As they continue to explore, Beckett finds a holographic recording left by one of the Ancients. She explains how the Ancients left Earth and came to the Pegasus Galaxy, seeding the human form of life on a thousand worlds. But then they set foot on a dark world where a terrible enemy slept: the Wraith. The enemy awoke and began feeding on the human-populated worlds like a great scourge, until only Atlantis remained. The shield withstood the assault of the enemy's weapons for many years, but finally the Ancients decided that the only way to preserve the last of their kind was to submerge the city. The remaining Ancients went through the Stargate and returned to Earth thousands of years ago to live out the remainder of their lives.Soon, however, the team realizes that the great city of the Ancients may be nearing destruction -- and because of their arrival. Two of the three Z.P.M.s that power the city are dead, and the third is almost there. By exploring the city and turning things on, they risk the complete failure of the shield that is holding back the ocean.The naquadah generators brought from Earth cannot generate nearly enough power to sustain the failing shield, and, as expected, there's not nearly enough power to gate back to Earth. But they can dial to other planets in the Pegasus Galaxy. A planet from the Ancient's local database is chosen, and Colonel Sumner leads a team to either find a new Z.P.M. or safe harbor for the expedition. Major Sheppard goes along, as does the young and enthusiastic Lieutenant Ford.They arrive in the dark on the planet Athos, where two young children are playing in the woods. They meet a man named Halling, who believes they are traders. Halling leads them back to the Athosian encampment and introduces the team to Teyla Emmagan, one of their leaders. She is a strong and beautiful woman, who is cautious about helping the strangers. Sheppard tries to get to know her. When the sun comes up it reveals the ruins of an old city nearby, which the Athosians do not visit for fear that it will bring the Wraith down upon them. Sumner leads a team to check it out, while Teyla shows Sheppard a series of cave drawings that tell of the last great Wraith attack on their world.The Wraith keep human-colonized worlds like Athos as feeding grounds, returning every so often to "cull their human herds" -- though sometimes not for hundreds of years at a time. Still, they return more frequently in smaller numbers to keep the Athosians living in fear. Though they possess advanced technology, the Athosians live as a simple people and move their camps around to try and avoid the great enemy. Teyla is surprised to hear that the visitors have never heard of the Wraith; they have visited many worlds through the Stargate, and have never met anyone who did not know about them.Back at the Stargate, Ford watches as the gate activates and three Wraith "dart" ships come soaring through. Teyla and Sheppard return from the cave while Sumner's team rushes back to the encampment.

Tunney wants McKay to attend a scientific demonstration that he claims will be the solution to global warming. Feeling bold, McKay asks Dr. Jennifer Keller to accompany him and she accepts. Upon reaching Earth, they are flown, by private leer jet, to a top-secret facility in the middle of a desert. Once there, McKay is shocked by Tunney's brazen claims that he's invented a device that can cool the Earth by venting excess heat from our space/time into another space/time - an idea McKay had already pursued two years earlier. Despite Rodney's mounting concerns over its safety, Tunney activates his new technology, dropping the heat contained inside the facility by 10 degrees. But when the device reaches this goal and will not disengage, McKay realizes he has to work fast or everyone trapped inside the premises will freeze to death within the hour.

A hive ship comes out of hyperspace directly over the city of Atlantis and transmit's a garbled message. Despite missing data, McKay is able to make out a reference to Dr. Keller's gene therapy and an urgent request for help. On high alert, Col. Sheppard and his team launch a cloaked puddle jumper to investigate. They board the ship to discover the entire crew in stasis, and a prerecorded message from their nemesis - Todd. In it he reveals that he and the crew were stricken with a disease - a complication of the gene therapy developed by Dr. Keller, which they had tried to self administer. Many died and the rest were put in stasis. Now, they need Atlantis's help. After much deliberation, Mr. Woolsey gives the go-ahead. Back on the hive ship Dr. Keller struggles with the complexities of Wraith physiology as the other team members begin to notice something very unsettling - the hive ship itself has somehow been impacted by the disease, with dire consequences for all on board.

When it's observed that Dr. Jennifer Keller is behaving very strangely, Dr. Carson Beckett is asked to examine her. But extensive testing reveals nothing abnormal and they fear she may be suffering from a mysterious psychological disorder. Unbeknownst to them, Keller has traded bodies with that of a notorious criminal, Neela Casol, and finds herself at the mercy of a village magistrate, on a distant planet, about to be executed for her crimes. McKay's investigation leads him to suspect that Dr. Keller and Neela have switched consciousnesses by means of an Ancient communications tool. In a race against time, Sheppard and his team must locate Keller, along with the alien device. But they'll need Neela's help to do it.
