William Shatner returns as Admiral James T. Kirk who is feeling old; the prospect of accompanying his old ship, the USS Enterprise--now a Starfleet Academy training ship--on a two-week cadet cruise is not making him feel any younger. But the training cruise becomes a deadly serious mission when his nemesis Khan Noonien Singh--genetic conqueror from late 20th century Earth--appears after years of exile. Hell bent on revenge he captures the Genesis Project, a device holding the power of creation itself, and plans the utter destruction of Kirk. Will Kirk survive with his crew intact?
