With the film a month away, we’re given a new international trailer for the upcoming blockbuster, Transformers: The Last Knight.

In the film, humans and Transformers are at war, while Optimus Prime is gone. But, the key to saving humanity’s future is buried in the secrets of the hidden history of Transformers on Earth.

“In Transformers: The Last Knight, the hunted will become heroes. Heroes will become villains. Only one world will survive: theirs, or ours,” says Paramount.

Transformers: The Last Knight hits theaters on June 21.
