With the grand opening of the Blackfoot Magic Casino only days away, the Henricksons make last-minute preparations under the skeptical eye of Tommy Flute, son of Bill's partner Jerry. As the feds probe the whereabouts of Roman Grant, Alby has a close encounter with Dale Tomasson, the state-appointed trustee of Juniper Creek's assets. At the compound, Adaleen shares a shocking secret with Nicki, who's under fire for opening a new bank account for Roman. Though her home-shopping business is thriving, Margie makes an on-air slip-up that prompts her boss Beverly to voice concerns about possible burnout. Worried for her safety, Lois offers Frank a piece of her fledgling bird-purveying business. Bill and Nicki's smarmy ex, J.J. Walker, work out an arrangement allowing Cara Lynn to stay at the Henrickson's while attending high school during the week. Ben lands a gig with his Christian rock band and ends up being called into backup duty for another.
As if normal family life isn't enough trouble, Bill Henrickson has everything in triple: three wives, three houses, three families. Bill's first and only legal wife is Barb but he also shares the bedroom with middle wife Nicki and youngest wife Margene. Bill also has three new adjoining houses, seven kids, and a booming hardware business. His closest friend and business partner at Home Plus, Don Embry, is also a polygamist. The series kicks in as Bill receives troublesome news about his father Frank, who lives in rural Utah in a fundamentalist community lead by Bill's father-in-law, the menacing "Prophet" Roman Grant.
Bill's younger brother Joey was once a star athlete in the NFL, but is now getting used to living in the compound with his wife Wanda. Bill's mother Lois is a descendant to the original founder of the Juniper Creek compound, and is still bitter for Roman Grant's hostile takeover for the leadership. Daveigh Chase plays Roman's latest wife, the child-bride Rhonda. Rounding out the cast are Amanda Seyfried as Bill and Barb's oldest daughter Sarah, Douglas Smith as Ben, the adoring son, and Jolean Wejbe as Tancy, the precocious 8-year-old.
