As a US Marine serving three tours in the Iraq War, Samantha "Sam" Lockyear survives two IED attacks and spends a lengthy time being tortured as a prisoner of war. Returning home, she lives and works at Libby's scrap yard, located in a remote part of a southwestern US desert. Due to her war experience, she suffers from posttraumatic stress disorder and severe headaches. She spends her days talking to Mike, her imaginary friend who is a gorilla. One afternoon, Libby stops by to let Sam know a wealthy man has offered to buy the property. That night, a flying saucer experiences engine trouble and crashes in the scrap yard. Sam believes it is a hallucination, but plays along and repairs the UFO's engine.
