Star Trek II: The Wrath of Khan is a 1982 American science fiction film released by Paramount Pictures. It is the second film based on Star Trek, and is a sequel to Star Trek: The Motion Picture (1979). The plot features Admiral James T. Kirk (William Shatner) and the crew of the starship USS Enterprise facing off against the genetically-engineered tyrant Khan Noonien Singh (Ricardo Montalbán), a character who first appeared in the 1967 Star Trek television series episode "Space Seed". When Khan escapes from a 15-year exile to exact revenge on Kirk, the crew of the Enterprise must stop him from acquiring a powerful terraforming device named Genesis. The film concludes with the death of the Enterprise's captain, Spock (Leonard Nimoy), beginning a story arc that continues with the 1984 film Star Trek III: The Search for Spock and concludes with 1986's Star Trek IV: The Voyage Home.
