Follow the Prophet is an American film that was written by and stars Robert Chimento, which was created to show how polygamist lifestyles affect the children involved. In the film, a young girl escaping from a polygamist cult is aided by an Army Colonel and a renegade female Sheriff who join forces to save an even younger girl from a secret "marriage" to the cult's leader.
Movies on shocking or controversial subjects work best when they stick to the facts and refrain from sensationalizing. Follow the Prophet doesn't refrain from much.
