Transformers

"You shoot, I'll drive!" .. Before time began, there was... the cube. We know not where it comes from, only that it holds the power to create worlds and fill them... with life. That is how our race was born. For a time we had lived in harmony, but like all great power, some wanted it for good... others, evil. And so, began the war. A war that ravages our planet until it was consumed by death. And the cube was lost to the far reaches of space. We step in across the galaxy hoping to find it and rebuild our home. Searching every star. Every world. And just when all hopes seem lost; message of a new discovery took us to an unknown planet called... Earth. But we were already too late.

High-school student Sam Witwicky buys his first car, who is actually the Autobot Bumblebee. Bumblebee defends Sam and his girlfriend Mikaela Banes from the Decepticon Barricade, before the other Autobots arrive on Earth. They are searching for the Allspark, and the war on Earth heats up as the Decepticons attack a United States military base in Qatar. Sam and Mikaela are taken by the top-secret agency Sector 7 to help stop the Decepticons, but when they learn the agency also intends to destroy the Autobots, they formulate their own plan to save the world.
