Output: In the near future, Lunar Industries has made a fortune after an oil crisis by building Sarang Station, an automated lunar facility to mine the alternative fuel helium3 from lunar soil, rich in the material. The facility is fully automated, requiring only a single human to maintain operations, oversee the harvesters, and launch canisters bound for Earth containing the extracted helium3. Sam Bell nears the end of his threeyear work contract at Sarang Station. Chronic communication problems have disabled his live feed from Earth and limit him to occasional recorded messages from his wife Tess, who was pregnant with their daughter Eve when he left. His only companion is an artificial intelligence named GERTY, who assists with the bases automation and provides comfort for him. Two weeks before his return to Earth, Sam suffers from hallucinations of a teenage girl. One such image distracts him while out recovering a helium3 canister from a harvester, causing him to crash his lunar rover into the harvester. Rapidly losing cabin air from the crash, Sam falls unconscious. Sam awakes in the base infirmary with no memory of the accident. He overhears GERTY receiving instructions from Lunar Industries to prevent him from leaving the base and to wait for the arrival of a rescue team. Suspicious, Sam manufactures a fake problem to persuade GERTY to let him outside. He travels to the crashed rover, where he finds his unconscious doppelganger. He brings the double back to the base and tends to his injuries. The two Sams start to wonder if one is a clone of the other. After a heated argument and physical altercation, they coerce GERTY into revealing that they are both clones of the original Sam Bell. GERTY activated the newest clone after the rover crash, and convinced him that he was at the beginning of his threeyear contract. The two Sams search the facility, discovering a secret vault containing hundreds of hibernating clones. They determine that Lunar Industries is unethically using clones of the original Sam Bell to avoid the cost of new astronauts. The elder Sam drives past the interference radius in a second rover and tries to call Tess on Earth. He instead makes contact with Eve, now 15 years old, who says Tess died some years ago. He hangs up when Eve tells her father offscreen, identified as Original Sam in closed captioning that someone is calling regarding Tess. The two Sams realize that the incoming rescue team will kill them both if they are found together. The newer Sam convinces GERTY to revive another clone, planning to leave the revived clones corpse in the crashed rover and send the older Sam to Earth in one of the helium3 transports. But the older Sam, with his health declining, knows that he will not live much longer, having learned that the clones are designed to break down at the end of the 3year contract. The older Sam suggests the younger Sam leave instead, and that he the older Sam, is placed back into the crashed rover to die so Lunar Industries will not suspect anything. Following GERTYs advice, the younger Sam reboots GERTY to wipe its records of the events. Before leaving, the younger clone programs a harvester to crash and wreck a jamming antenna, thereby enabling live communications with Earth. The older Sam, back in the crippled rover, remains conscious long enough to watch the launch of the transport carrying the younger Sam to Earth. The rescue team finds the newly awakened clone in the medical bay and the body of the older Sam and are fooled. The transport arrives at Earth, and over the films credits, news reports describe how Sams testimony on Lunar Industries activities has stirred up an enormous controversy, and the companys unethical practices have plummeted the companys stock.
