Two species at war: one of flesh and blood, the other of metal. Humans and Transformers are at war and Optimus Prime is gone. The key to saving our future is buried in the secrets of the past, in the hidden history of the Transformers on Earth. Saving our world is in the hands of a unique alliance: Cade Yeager, Bumblebee, an English Lord ( Sir Anthony Hopkins ), and a professor at the University of Oxford ( Laura Haddock ). There is a moment in the life of every human being when we receive the call to make a difference.
