The film is based on the extraordinary true story of Rena Chynoweth, a brave survivor and former wife of a manipulative polygamist group leader, who escaped a life of oppression and dedicated herself to freeing others. When Rena and her family arrive in Colonia Le Baron, a secluded polygamist Mormon settlement in Mexico, they are commanded to relinquish all their earthly possessions and devote themselves to the doctrines of the LeBaron brothers, Ervil and Joel. However, as the brothers’ insatiable thirst for power ignites growing discord, the community fractures, and Rena’s family aligns with Ervil.
