Collection of four classic sci-fi adventures based on the 1960s TV series. In 'Star Trek: The Motion Picture' (1979) the crew of the USS Enterprise come out of retirement in the 23rd century when Earth is threatened by a massive energy field. Captain James T. Kirk (William Shatner), now a Starfleet Admiral, Spock (Leonard Nimoy), Bones (DeForest Kelley) and the rest of the starship's crew assemble to investigate the dangerous energy cloud, but can they find a way to stop it from destroying the planet? In 'Star Trek II - The Wrath of Khan' (1982) the crew of the starship Enterprise encounter Khan (Ricardo Montalban), an old foe whom Captain Kirk previously banished to a far corner of the universe. A selectively bred supervillain, Khan threatens to reverse creation with his Genesis Machine, but can Kirk and his crew stop him? In 'Star Trek III - The Search for Spock' (1984) Kirk disregards Starfleet orders and steals the USS Enterprise to venture out on a mission to find the body of Spock. However, on their voyage the crew, including Dr 'Bones' McCoy, who appears to have absorbed part of Spock's spirit, are impeded by marauding Klingons, commanded by Kruge (Christopher Lloyd), who are plotting to steal the secrets of the Genesis Device. Finally, in 'Star Trek IV - The Voyage Home' (1986) the crew of the destroyed USS Enterprise abandon the 23rd century for Earth in the year 1986. In order to save the planet from a rogue space probe in the future, the starship's crew must travel back to the 20th century to find the only creature capable of communicating with it: humpback whales.
