The final trailer for "Transformers: The Last Knight" has arrived, in all its robot vs robot glory. In it, we learn Optimus Prime's motivations for standing against Bumblebee and his former allies, catch more glimpses of the Transformers' secret history on Earth and Cybertron both, all mixed with some serious robotic violence.

With Optimus Prime gone following the events of 2014’s “Age of Extinction,” a war for survival has broken out between humanity and the Transformers, leading to a grim dystopia where robots pursue children through bombed-out cities. “The Last Knight” promises to answer one of the core questions of the Transformers universe: Why do these robots in disguise keep returning to Earth?

“The Last Knight” shatters the core myths of the Transformers franchise, and redefines what it means to be a hero. Humans and Transformers are at war, Optimus Prime is gone. The key to saving our future lies buried in the secrets of the past, in the hidden history of Transformers on Earth. Saving our world falls upon the shoulders of an unlikely alliance: Cade Yeager (Mark Wahlberg); Bumblebee; an English Lord (Sir Anthony Hopkins); and an Oxford Professor (Laura Haddock).

There comes a moment in everyone’s life when we are called upon to make a difference. In Transformers: The Last Knight, the hunted will become heroes. Heroes will become villains. Only one world will survive: theirs, or ours.

The film sets the stage for the planned expansion of the $3.78 billion franchise that includes a Bumblebee spinoff slated for 2018, another Transformers sequel in 2019, and a possible origin movie for the constantly warring Autobots and Decepticons.
