Darah, the daughter of polygamous cult leader Warren Keegan, seeks to break free from her father's grip and reconnect with her sister. However, her plans are thwarted when Warren and his three wives kidnap her. The FBI is on Warren's trail after he attacked a federal officer. Using the satellite dish he installed on his RV, Matt and Emily track down Darah and her captors. They learn from Darah's sister, who escaped from Warren's clutches, that he believes having four wives will save him from an impending apocalypse.
