Star Trek II: The Wrath of Khan
With the assistance of the Enterprise crew, Admiral Kirk must stop an old nemesis, Khan Noonien Singh, from using the life-generating Genesis Device as the ultimate weapon.
Newly promoted Admiral James T. Kirk (William Shatner) comes face to face with his nemesis, the genetically superior Khan (Ricardo Montalban), who is seeking revenge for having been imprisoned on a desolate planet. A battle ensues over control of the Genesis Device, a top-secret Starfleet project enabling entire planets to be transformed into life-supporting worlds. While Mr. Spock (Leonard Nimoy) mentors the young Vulcan Lt. Saavik (Kirstie Alley), Kirk must battle Khan to the bitter end.
