Major Bill Cage is an officer who has never seen a day of combat when he is unceremoniously demoted and dropped into combat. Cage is killed within minutes, managing to take an alpha alien down with him. He awakens back at the beginning of the same day and is forced to fight and die again... and again - as physical contact with the alien has thrown him into a time loop.
Royal Marine A.J Budd awakes in a mysterious house and is forced to fight for his life everyday against grotesque inhuman opponents. Trapped alone in an unchanging prison of unbreakable routines, he must kill every day or die himself. As days stretch into years, the isolation and unceasing violence threaten his very soul.
