Life for Dexter is returning to normal. He's taking care of his son with the help of Angel Batista's sister Jamie. He dispatches two EMTs who have been killing patients to harvest their organs and he's looking forward to his high school 20th anniversary reunion. Not surprisingly, Dexter was something of an outsider in school but one girl, Janet, was at least nice to him. She dated and eventually married the schools star quarterback Joe Walker but committed suicide after they were married. Dexter is certain that Joe killed her and his main interest in the reunion weekend is to get a DNA sample from him. Elsewhere, Maria LaGuerta has been promoted to Captain and she and Angel are divorced. They're still friends and she is recommending him as her replacement as Lieutenant. Deb and Quinn are still living together and he is getting ready to pop the question - only to be interrupted in a restaurant in an unusual way. Finally, the entire squad has to deal with the disappearance of a roadside fruit seller. From the evidence at the scene, they think the man may have been disemboweled. When his body washes up on shore, they find something has been put into his torso.
