Transformers: Revenge of the Fallen (2009)

On the run in the year 1987, Bumblebee the Autobot seeks refuge in a junkyard in a small California beach town. Charlie, on the brink of turning 18 years old and trying to find her place in the world, soon discovers the battle-scarred and broken Bumblebee. When Charlie revives him, she quickly learns that this is no ordinary yellow Volkswagen.

Optimus Prime and the Autobots team up with a down on his luck young man, an aspiring historian and with a powerful faction of Transformers known as the Maximals to combat a sinister force from outer space that threatens the Earth and all of mankind.

The fate of humanity is at stake when two races of robots, the good Autobots and the villainous Decepticons, bring their war to Earth. The robots have the ability to change into different mechanical objects as they seek the key to ultimate power, but only human Sam Witwicky can save the world from total destruction.

After an epic battle, a great city lies in ruins, but the Earth itself is saved. As humanity begins to pick up the pieces, a shadowy group emerges to try to take control of history. Meanwhile, an ancient and powerful new menace sets its sights on Earth. A new group of humans, led by Cade Yeager (Mark Wahlberg), helps Optimus Prime (Peter Cullen) and the Autobots rise up to meet their most fearsome challenge yet: a worldwide war of good versus evil.

Humans are at war with the Transformers, and Optimus Prime is gone. The key to saving the future lies buried in the secrets of the past and the hidden history of Transformers on Earth. Now, it's up to the unlikely alliance of inventor Cade Yeager, Bumblebee, an English lord and an Oxford professor to save the world.
