Moon
Sam Bell (Sam Rockwell) is an employee contracted by the company Lunar Industries to extract helium-3 from lunar soil for much-needed clean energy back on Earth, leaving behind his wife Tess and 3 year old daughter Eve. He is stationed for three years at the largely automated 'Sarang' ('Sarang' means 'love' in Korean) lunar base with only a robotic assistant named GERTY (voiced by Kevin Spacey) for company; a chronic communications failure limits him to only occasional recorded transmissions to and from Earth. Two weeks before completing his contract, he begins to hallucinate, briefly seeing a teenage girl on the station. During a routine rover excursion to extract helium-3 from a harvesting machine, he sees the same girl standing on the lunar surface. Distracted, he crashes the rover into the harvester.
Sam awakens in the infirmary and GERTY tells him that he is recovering from injuries sustained in an accident. Sam's suspicion is aroused when he eavesdrops on a live communication between GERTY and Lunar Industries headquarters, and that GERTY will not allow outside the base. A message with Lunar Industries executives inform him that a rescue crew is on the way to repair the harvester and take him home. Sam sabotages the base to convince GERTY to allow him outside to repair the fault. Instead Sam goes to investigate the damaged harvester, where he finds someone barely alive in the crashed rover: himself.
The two Sam's struggle to come to grips with the existence of each other, each believing the other to be a clone of himself, with the first Sam's physical and mental state beginning to rapidly deteriorate. The second Sam reflects himself at the beginning of his contract; sharp, headstrong and with a short temper. Unable to find answers in the base and from a uncooperative GERTY, they investigate the source of the bases communication problem, and venture outside of the bases perimeter. Outside they find a series of antennas jamming direct live communication with Earth. The first Sam becomes ill and returns to base where, with the aid of GERTY confirms their cloning conspiracy, watching video logs of previous Sam bell clones: working, becoming ill, getting into the "hibernation" pod to return home, and being incinerated. Now with a better understanding the nature of his existence, he explores the death chamber further, discovering a hidden chamber beneath it. The two Sam's explore the chamber together, finding an extensive cache of clones. The first Sam takes a rover out beyond the jammers, and establishes an up-link with the Bell residence. He speaks with Eve, now 15 years old, who was the girl he had seen previously in his hallucinations. He learns that Tess has died "some years ago", and that the original Sam Bell is alive on Earth.
With only a few hours before the "rescue" team arrives, the two Sams realize that if they are discovered together, they will both be killed. The second Sam makes a plan to launch the first Sam back to Earth in the helium delivery vessel, activating another clone to take the first Sam's place in the damaged rover. Prior to enacting their plan, the first Sam realising that he is near death, and insists that the second Sam escape, while he returns to the rover to die. To cover up the second Sam's existence, GERTY permits Sam to wipe his memory and reboot him. After reprogramming the helium harvesters to crash into the jammers, the second Sam launches his escape, which the first Sam sees in his final moments. With the jammer disabled, the base computer finally registers that a live up-link has been established. As the second Sam approaches Earth, voice-overs begin detailing Lunar Industries executives' arraignment on crimes against humanity.
