While Bill seeks protection against the religious compound led by Roman Grant, things heat up between the sister-wives over Margene's overtly sexual behavior. Roman "The Prophet" asks Bill's father to act as a go-between to deliver a message to his son, and the Hendricksons get together for a family dinner with Bill's business partner and his three wives. Meanwhile, Margene pressures Bill about buying her a car and Ben goes out on a date with a girl that seems too mature for him.

Bill gets a new home security system, Nicki throws a birthday party, new neighbours move in, and Margene meets her mother-in-law. Meanwhile, there's a break-in in Bill's hardware store.
