A 14 year old girl is found barely living in the desert. She escaped from the custody of a self-announced "prophet" who forced her to become his 73rd wife. As the FBI finds out that the mother of the girl surrendered her daughter to the "prophet", more mysteries become obvious. Charly applies an relational network model and finds out that it represents an inbreeding chart displaying the mating behavior of the "prophet" and his followers. It turns out that the girl and her mother have the same father and that the girl was only forced to be with the "prophet" in order to lower the inbreeding coefficient of their offspring so that a cleaner bloodline can be established. The "prophet" flees with his followers into a condemned house in the desert and has to face the armed forces of the FBI in a show down.
