Release date: 19 April 2013, United States
As with all overviews, ALL THE SPOILERS ahead. Some movies warrant just a few paragraphs, but it turns out this is a rather complicated plot.
Oblivion opens 50 years after an alien invasion, during which a great many things happened.
- Aliens called “Scavs” hammered the moon into huge clustered fragments
- (In turn) Doing massive ecological damage to the Earth
- The humans retaliated with nuclear weapons
- The Earth became contaminated with radiation
- Most of humanity had to leave the planet to colonize Titan
- Massive hydro-rigs were set up in the oceans that convert seawater into energy
- Semi-autonomous flying robots called drones patrol and defend the hydro-rigs from the remaining Scavs, who attempt to destroy the drones and hydro-rigs
- A massive tetrahedral spaceship called the Tet was put in orbit around the earth to serve as command and control for pairs of humans who live as a couple and work as a team in their section to monitor and protect both the hydro-rigs and the drones
- One member of these teams stays in their sky home, called the Tower, to monitor activity and relay information to and from the Tet
- The other member of these teams, the Tech, operates a “bubbleship” to patrol the sector to which they are assigned
One team, Victoria and Jack, are two weeks away from retirement when they are awoken one night by a massive explosion. It is one of their hydro-rigs, sabotaged by Scavs in their section. While investigating the wreckage, they detect a strange radio signal. Jack traces it to its source, discovering a repeater in the ruined Empire State Building broadcasting a set of coordinates off-planet. Later he spies a vessel landing at the broadcast coordinates. He visits the crashed vessel to find it is part of a pre-war human spacecraft, the sleeping pod of the Odyssey. Within are hibernation chambers, but only one crewmember is alive. Jack recovers it as drones show up to destroy them. At the Tower, Jack and Victoria revive its occupant, Julia. The next morning Julia travels with Jack back to the crash site to fetch the flight recorder, but both are taken captive by Scavs.
In captivity Jack learns the horrible truth…
- The Scavs are actually the only humans left after the war
- The Tet, drones, and hydro-rigs are the alien technology
- Jack and Victoria are the tools of the aliens defending their tech from the rest of humanity
- Scavs remote-controlled the Odyssey to crash in order to scavenge its nuclear fuel for a bomb to be delivered to the Tet in a captured Drone
Victoria, unaware, sends drones to save Jack, forcing the Scavs to release Jack and Julia. The leader Beech encourages Jack to visit the forbidden radiation zones to confirm the truth. Julie further reveals…
- The Odyssey was originally en route to Titan when it was intercepted by the alien Tet
- Jack and Victoria were once part of the Odyssey crew as well
- Jack and Julia were husband and wife
Through a remote-controlled bubbleship camera, Victoria observes them kissing and this drives her to betray Jack and Julie to the Tet. The Tet activates a Drone and sends it to kill them all, but it only kills Victoria before Julia destroys it. Traveling to another sector, Jack sees a clone of himself appear in a similar bubbleship, to service a Drone. They fight and the clone is killed, and Julia is wounded in the melee. Jack gets into the clone’s bubbleship and travels to its Tower, where he meets a Victoria clone, and he realizes that the planet must be populated by huge numbers of these clones. He fetches a medkit and returns to Julia. He takes her to recover in a log cabin in a lush valley he has been keeping secret from Victoria for a long time. After she heals, he returns to the Scavs, and helps them reprogram their captured Drone, but the Scav enclave is largely destroyed by other drones sent by the Tet.
They load the bomb into a hibernation chamber, appear to seal Julia inside, load it onto a bubbleship, and fly to the Tet. En route he plays the flight recording from the Odyssey to learn…
- When the Odyssey originally approached the Tet, Victoria and Jack were pilot and copilot
- When they were caught in the Tet’s tractor beam, they ejected the sleeping pod with the remainder of the crew to protect them
Finally, in the bowels of the Tet, he…
- Sees the clone vats where more Jacks and Victorias are being grown
- Faces the horrible alien intelligence
- Awakens the person in the hibernation chamber, which—surprise—is Beech, not Julia
- Explodes the bomb, destroying the Tet
Back on Earth, Julia is awakes in a different hibernation chamber at the lush log cabin, as part of Jack’s duplicitous plan to save her. She gives birth to a daughter, and three years later is found by one of the Jack clones, accompanied by a group of the surviving Scavs.
