邪恶的可汗逃脱十五年前被寇克船长拘禁的星球,他本人是一位智勇双全的领袖,但此刻已变成一个邪恶的狂人,他誓言要向寇克船长讨回血仇。于是他先劫持了一艘联邦战舰,后又偷取了寇克船长的儿子和旧情人制造的毁灭性武器。并引诱企业号投入他精心设计的圈套……It is the 23rd century. Admiral James T. Kirk is an instructor at Starfleet Academy and feeling old; the prospect of attending his ship, the USS Enterprise--now a training ship--on a two-week cadet cruise does not make him feel any younger. But the training cruise becomes a deadly serious mission when his nemesis Khan Noonien Singh--infamous conqueror from late 20th century Earth--appears after years of exile. Khan later revealed that the planet Ceti Alpha VI exploded, and shifted the orbit of the fifth planet as a Mars-like haven. He begins capturing Project Genesis, a top secret device holding the power of creation itself, and schemes the utter destruction of Kirk.
