Documentary providing access to the community of Rockland Ranch in the middle of the Utah desert, where 14 Mormon families have made a home for themselves. Half the men here are polygamists, including father-of-16 Enoch Foster. He is one of the most influential men in the community and has two wives, who adore him and each other. But their family is set to expand again, with baby number 17 on the way - and Enoch is also courting a third wife, 25-year-old nanny Lydia.
