Bumblebee wields a formidable-looking hammer in the latest poster for "Transformers: The Last Knight." However, whether that weapon is a match for Optimus Prime's sword remains to be seen.

The fifth installment of Paramount Pictures' blockbuster franchise reveals a war for survival has broken out between humanity and the Transformers following the events of 2014's "Age of Extinction," leading to a grim dystopia where robots pursue children through bombed-out cities. Directed by Michael Bay, “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.

Opening June 23, "Transformers: The Last Knight" stars franchise veterans Mark Wahlberg, Stanley Tucci, Josh Duhamel, Tyrese Gibson and John Turturro, joined by newcomers Isabela Moner, Liam Garrigan, Jerrod Carmichael, Mitch Pileggi, Laura Haddock, Santago Cabrera and Anthony Hopkins.
