Meanwhile, Nicki gets news that seems too good to be true; and a late-breaking polygamist scandal forces Bill and his three wives to rethink their bold post-election plans.

After being elected state senator, Bill Henrikson announces that he is a polygamist, and he and his families are attacked from every side; Alby Grant returns from living in the desert with the idea of purifying the compound and getting revenge.

The Henricksons' holiday cheer is tested by family revelations. Alby's purification of Juniper Creek leads to a defection.

Bill fights for his right to be sworn in as senator; Barb, Nicki, and Margene struggle with personal revelations and changed public profiles.
