This documentary series delves into the history of a splinter group of fundamentalist Mormon sect members. For decades, they committed a deadly wave of violence and abuse in the name of their fanatical prophet, Ervil LeBaron. He hid with his followers in the southwest and Mexico. Now former members of the infamous cult are telling the true story behind the series of murderous crimes. The series features interviews with surviving ex-members, including several of LeBaron's children, who talk about their experiences growing up under their father's rule.
