It is the 23rd century. The Federation starship U.S.S. Enterprise is on routine training maneuvers, and Admiral James T. Kirk (William Shatner) seems resigned to the fact that this inspection may well be the last space mission of his career. But Khan is back. Aided by his exiled band of genetic supermen, Khan (Ricardo Montalban)-brilliant renegade of 20th century Earth-has raided Space Station Regular One, stolen a top-secret device called Project Genesis, wrested control of another Federation starship, and now schemes to set a most deadly trap for his old enemy Kirk....with the threat of a universal Armageddon! Co-starring Kirstie Alley (Cheers) in her stunning motion picture debut.
