Transformers: Dark of the Moon is the third film in the series. A sequel, which is set three years, in 2012, after the events of Revenge of the Fallen, when the war on Cybertron between the Autobots and Decepticons appears lost to the Autobots, their leader, Sentinel Prime (Leonard Nimoy), attempts to launch the Ark, an Autobot ship from their planet, containing the technology that could have saved his race. However, it crash lands on Earth’s moon in 1961, prompting President John F. Kennedy to make his famous promise to the nation to put a man on the Moon. The 1969 Apollo 11 moon landing was actually an investigation of the spacecraft. As Sam Witwicky goes into adulthood with a new girlfriend named Carly Spencer (Rosie Huntington-Whiteley), the Autobots learn of the Ark and of Sentinel Prime. Thus, Sentinel Prime is brought back to Earth, and revived using the Matrix of Leadership. Optimus Prime convinces America’s leadership that they must protect Sentinel Prime, and his “pillars”, which can help transport matter through time and space. Later, Sentinel betrays the Autobots as he allies with the Decepticons, killing Ironhide in the process, and reveals to have made a deal with the Decepticons to bring back Cybertron. America’s leaders decide to send the Autobots to another planet, wanting to avoid war and granting Sentinel and the Decepticons’ forced request. But as the Autobots leave, the Decepticons shoot their ship down, believing that they had killed all of the Autobots onboard it. With the Autobots gone, Sentinel Prime activates the pillars, andChicago is seized by the Decepticons and their vicious/evil human ally, Dylan Gould (Patrick Dempsey). Thus begins the reproduction of Cybertron, at the cost of Earth, its resources and humanity. But, it is later revealed that the Autobots had faked their deaths, and a battle ensues between the Autobots and Decepticons in Chicago, for one final stand where Sentinel, Megatron, Starscream, Soundwave, Laserbeak (Keith Szarabajka), Barricade, Shockwave (Frank Welker), Que (George Coe), and Dylan all lose their lives and Cybertron is destroyed as the remaining Autobots vowing never to forsake it.
