A Cybertronian spacecraft, known as the Ark, was the last ship to escape Cybertron, a planet devastated by wars.
Piloted by Sentinel Prime, it carries "the pillars" technology that could save the Cybertronians once and for all.
The Autobots, led by Optimus Prime, need to recover the pillars before the evil Decepticons get their hands on them and Sentinel's damaged body.
Sam Witwicky (Shia LaBeouf) fears the Decepticons are rising again.
He knows he must get to Optimus Prime and inform him of the dangers before their enemies have the power to change the world.
But it is not all about machines; Sam, his girlfriend Carly (Rosie Huntington-Whiteley), and their comrades make up a formidable fighting force along with the Autobots.
If the Decepticons want to win the war they'll need all their powers, and more.
