To enjoy a science fiction set in a post-apocalyptic period, watch Oblivion online. The film begins in 2077. Planet Earth is in ruins after extraterrestrial invaders, the Scavs, triggered a war. Consequently human beings are being moved to a moon named Titan. The relocation project requires massive amounts of energy that is coming from generators which are exploiting fusion energy. To protect the generators from the Scavs are Jack and Vika who also double up as lovers. They are just among a few of the human beings still remaining in the world. The two are also being aided in their duties by drones.
Though Jack has had his memory wiped, he sometimes has visions of having spent time with an unidentified woman prior to the war.
When Jack scours the remains a spacecraft that had crashed before the invasion, he comes across human beings who have survived by hibernating. One of these is the woman he has been seeing in his visions and her name is Julia. Just then a drone attacks killing the hibernating survivors. Jack however manages to save Julia.
When the two return some time later to get the flight recorder the Scavs capture them. The Scavs however turn out not to be aliens but humans who survived the invasion. Beech, their leader, wants the assistance of Jack in destroying an alien ship named Tet. Eventually the two are released by Beech.
On their way back after their capture Julia informs Jack that they were married. But when Jack tries to access his duty station, he is denied entry by Vika. More complications are to arise in Oblivion as Jack and other surviving humans try to outfox the Scavs.
