The war on Cybertron between the Autobots and Decepticons appears lost. The leader of the Autobots, Sentinel Prime, attempts to launch the Ark from their planet, with technology that could have saved his kind. The Ark is attacked and crashes on Earth's moon in 1961, when President John F. Kennedy makes his famous promise to the nation to put a man on the moon. The 1969 NASA moon landing is actually an investigation of the wrecked spacecraft. As Sam Witwicky goes into adulthood and tries to move on from Mikaela, the Autobots learn of a Cybertronian spacecraft on the Moon. They race against the Decepticons to be first to find it and learn its secrets.
Rated PG-13 by the Motion Picture Association of America for intense prolonged sequences of sci-fi action violence, mayhem, destruction and for language, some sexuality and innuendo.
