Transformers: Age of Extinction (2014)

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.

Two years after he and his Autobot friends saved the Earth from the Decepticons, Sam Witwicky (Shia LaBeouf) faces a new battle: college. Meanwhile, Optimus Prime and the Autobots are working with a secret military organization and trying to make a home for themselves on Earth. When an ancient Decepticon known as The Fallen rises up to wreak vengeance, Sam and his girlfriend, Mikaela, must figure out the history of the Transformers on Earth and find a way to defeat The Fallen once and for all.

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.
