No Overflix. At the Mountain Rock Church in South Carolina, Pastor Raimund Melz leads a small Christian cult that justifies brutal actions like child abuse with the words of the Old Testament. Documentarian Ondi Timoner focuses on one family in particular, who left the church with plans to file charges against Melz before eventually checking into a one-of-a-kind cult treatment center. Timoner's film follows their journey as they receive psychological help and then return home to confront their former pastor.
