Oblivion

On a spectacular future Earth that has evolved beyond recognition, one man’s confrontation with the past will lead him on a journey of redemption and discovery as he battles to save mankind.

Jack Harper (Cruise) is one of the last few drone repairmen stationed on Earth. Part of a massive operation to extract vital resources after decades of war with a terrifying threat known as the Scavs, Jack’s mission is nearly complete.

Living in and patrolling the breathtaking skies from thousands of feet above, his soaring existence is brought crashing down when he rescues a beautiful stranger from a downed spacecraft. Her arrival triggers a chain of events that forces him to question everything he knows and puts the fate of humanity in his hands.

Set on a future Earth, civilization lives above the clouds and scavengers collect ancient artifacts from the polluted surface below. An earthbound soldier, who is stuck there repairing drones that patrol and blast a savage alien life form, encounters a beautiful woman who crashed in a craft and they have an experience that forces him to question his world view.

After a court-martial, a battle-damaged soldier is sent to a desolate planet and is assigned to patrol the bleak landscape in an effort to destroy the last vestiges of a primitive alien race. When a mysterious traveler arrives unexpectedly, their lives become inextricably linked as they are forced to question everything they know about this world and themselves.
