Sons of the Prophet

S4, E5: Raymond Jeffs, son of the infamous FLDS prophet, Warren Jeffs, pleads for the girls' help with getting his only brother, Isaac, out of the group. The team quickly discovers Isaac is closely monitored by a group of men who are taught to fight outsiders at all costs, and tempers flare when the plan to break him out is exposed. Later, Mattie, a young woman who recently escaped the FLDS, reunites with the mother she left behind in the group.
