their time machine. The filmmakers regroup and flee, chased by the Lunology members. Unable to outrun the Lunology members, the filmmakers stop their car and demand an explanation. Instead, the Lunology members' car takes off into the sky. Stunned and unsure of what happened, the filmmakers debate what to do next. A note leads them to David James, a former member of the lunar colony who explains its history. The lunar colony and Church of Lunology are separate; the colonists are from the future, and Lunology cultists are normal people. Using the lunar rock, J. Ari Hilliard invents immortality and time travel, and, on December 21, 2012, he sends the first mission back to 350 BC, where they begin changing the timeline. This created unintended changes, resulting in a desire to repeatedly tinker with the timeline. Dissidents opposed this, fearing it could result in more unintended changes and weakened dimensional barriers between the changed timelines. The scientists' rationalizations became Lunology. Hilliard, himself disillusioned, left the lunar colony and tried to reveal the truth, to no avail. Convinced that immortality was too great a power for any one person, he tried to murder himself before he could become immortal. The lunar colony, wise to his plans, prevented his first attempt in 1947, when he was born. His next attempt resulted in the Roswell UFO incident, as he fled the lunar colony back to Earth with the crystal. The crystal exists only in one place across all timelines, so the lunar colony must recover it before they can time travel any further. When Lunologists track down James, the filmmakers flee. Dr. Raymond and Larson both disappear. When the filmmakers return to the spot where they found the harness, it seems to have changed. James recommends they give the crystal to Hilliard himself. The CEO of Lunology plays stupid, but they set up a meeting with Hilliard. At the meeting, James reveals himself as the immortal, future version of Hilliard. Hilliard says the crystal was a test; James comes to the realization that they failed the test and kills Hilliard, his alternative self, to prevent further time travel. In a possible alternate timeline, people discover the documentary footage. Meanwhile, the anachronistic man from the Polaroid walks into the meeting room, with both timelines intertwining behind him, and picks up the crystal. He also picks up the camera and stares into it, with his
