Oblivion

In 2017, aliens known as Scavengers (mostly "Scavs" in dialogue) attack Earth and destroy the Moon, triggering global natural disasters. Although humanity wins the war using nuclear weapons, Earth is left uninhabitable. Sixty years later, the remnants of humanity have relocated to a colony on Saturn's largest moon, Titan, except for Unit 49—technician Jack and his communications officer Victoria ("Vika")—who are scheduled to join them in two weeks. The pair oversee hydro rigs that convert seawater into fusion energy for the Tet, the last remaining human colony ship in orbit. Though Jack and Victoria are romantically involved and have had their memories erased for security reasons, Jack experiences recurring dreams of an unknown woman. He also secretly visits a hidden, verdant valley where he has built a lakeside cabin and collects relics of Earth's past. While investigating a missing combat drone—autonomous, highly advanced, and heavily armed—Jack is nearly captured by Scavengers. Later, he discovers the Scavengers are transmitting a signal into space. A module of a NASA spaceship crash-lands at the signal's coordinates, carrying five humans in suspended animation ("delta sleep"), including the woman from Jack's dreams. Drones arrive and terminate four of them, but Jack protects the unconscious woman and brings her pod back to Unit 49's base. After reviving her, Jack and Victoria learn that the woman, Julia, was aboard the Odyssey spaceship and has been in stasis since 2017. Julia insists on recovering the ship's flight recorder. She and Jack are captured by Scavengers and brought to the Raven Rock Mountain Complex. Their leader, Malcolm, reveals that the Scavengers are surviving humans. Malcolm needs Jack to reprogram a captured drone to deliver a nuclear bomb, built from the Odyssey's reactor, to the Tet. Jack refuses, so Malcolm releases him and Julia, urging him to seek the truth in the radiation zone, which is off-limits. Julia helps Jack recall that she is his wife, and fragments of his memories begin to return. When they arrive back at Unit 49, a devastated Victoria informs Sally, the Tet's mission controller, that she and Jack are no longer an "effective team". A drone activates and kills Victoria. Jack and Julia destroy the drone but crash their aircraft inside the radiation zone. There, they encounter another version of Jack ("Jack-52") who arrives to repair the drone. Jack subdues him, but Julia is seriously injured in the fight. Jack impersonates his clone to infiltrate Unit 52, meets "Victoria-52", and steals medical equipment for Julia. They rest at his cabin. At Raven Rock, Malcolm reveals the truth: humanity lost the war, and the Tet is an extraterrestrial intelligence harvesting Earth's resources. After the Moon's destruction, the Tet deployed thousands of clones of astronaut Jack Harper—brainwashed into obedience—to exterminate the remaining humans. Malcolm had assumed that these clones were inhuman until witnessing Jack show interest in a discarded book of ancient poems, hinting at lingering humanity. Jack reprograms the captured drone, but it is destroyed in a surprise attack by other drones, leaving Malcolm badly wounded. Jack and Julia resolve to deliver the bomb; Julia enters a stasis pod. En route, Jack listens to the Odyssey's flight recorder, which reveals the original Jack Harper and Victoria were astronauts sent to explore Titan before being confronted by the Tet. The pair were captured but not before Jack ejected the remaining crew—including Julia—in stasis pods to protect them. Jack gains access to the Tet by claiming he is delivering Julia, as previously instructed; instead, the stasis pod contains a dying Malcolm. They detonate the bomb, destroying the Tet and themselves. Julia later awakens at the cabin. Three years later, Julia lives there and it is revealed she had a daughter with Jack. A group of Raven Rock survivors arrives with Jack-52, who has begun regaining fragments of his identity.
