An alien race has hit earth in a relentless assault, unbeatable by any military unit in the world. Major William Cage (Cruise) is an officer who has never seen a day of combat when he fell without ceremonies on a suicide mission. Killed in a matter of minutes, the cage is now inexplicably thrown into a time loop, forcing it to live the same brutal fight over and over again, fighting and dying again… And again. But with each battle, the cage can engage opponents with increasing skill, along with special forces, Warrior Rita Vrataski (Blunt). And, as the cage and Vrataski take the fight to the aliens, each repeated encounter is one more step closer to defeat the enemy!
