Twenty-five years after the mass suicide of the religious cult Heaven's Veil, documentary filmmaker Maggie Price and her brother Christian contact the sole survivor, Sarah Hope, to film a documentary about what really happened. Sarah, who was five years old at the time, accepts Maggie's claim that there is footage from the suicide that has never been found. Christian explains that their father was the FBI agent who led the investigation. Shortly after discovering the mass suicide, he committed suicide himself, driving the siblings to investigate.
