In The Endless, filmmaking duo Justin Benson and Aaron Moorhead play two brothers—also named Justin and Aaron—who were raised by a UFO death cult. So growing up wasn’t particularly pleasant, as the cult believes in mass suicide and an impending rapture by an extraterrestrial force. While Justin and Aaron have since escaped and been deprogrammed, life in the outside world isn’t that great, either—they’re house cleaners sharing a studio apartment in LA. The younger Aaron longs to return to “the commune,” and when they receive a mysterious videotape from a cult member, Aaron convinces Justin to return for a weekend visit.
