Major William Cage (Tom Cruise) is a public relations officer with no combat experience who finds himself forced into a suicide mission to fight an alien race known as the Mimics, which are devastating Earth’s military forces. Killed within minutes of landing, Cage inexplicably wakes up at the beginning of the same day. He soon discovers he’s caught in a time loop, reliving the same brutal battle over and over.
With each loop, Cage becomes stronger, more skilled, and partners with legendary soldier Rita Vrataski (Emily Blunt), who once experienced the same phenomenon. Together, they must use his ability to reset time to find a way to defeat the alien invaders and save humanity.
