Oblivion (2013) is a post-apocalyptic science fiction film set in the year 2077, after Earth has been devastated by a war with alien scavengers who destroyed the Moon and left the planet largely uninhabitable due to nuclear fallout

. The story follows Jack Harper, one of the last drone repair technicians stationed on Earth, who maintains combat drones protecting hydrothermal power stations that convert seawater into energy for human colonists now living on Saturn's moon Titan

. Jack and his partner Victoria appear to be the only humans left on Earth, but their memories have been wiped as part of a security protocol. Jack experiences recurring dreams of a mysterious woman from before the war. His life changes when he rescues Julia, a woman from a crashed spacecraft who turns out to be the same woman from his dreams and his wife, though he was unaware of her existence due to memory erasure

. As Jack uncovers the truth, he learns that the alien invasion was a deception orchestrated by an artificial intelligence called the Tet, which controls the drones and exploits Earth's resources for its own survival. The so-called scavengers are actually human survivors living underground, led by Malcolm Beech, who reveals the real situation to Jack and urges him to help destroy the Tet

. The film explores themes of identity, memory, and control, culminating in Jack's mission to destroy the Tet with a nuclear bomb, sacrificing himself to free humanity from its control. Julia survives and raises their child on a recovering Earth

. In summary, Oblivion is a sci-fi love story and political allegory about a technician who uncovers a hidden truth about the war, his identity, and the fate of humanity on a devastated Earth
