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.
