Passion, jealousy, treachery, greed. Everyone has something to hide in the biggest, boldest season yet of this provocative series. Bill Henrickson (Bill Paxton) returns as the enterprising, suburban polygamist who has more than his hands full, with three wives (Jeanne Tripplehorn, Chloë Sevigny, and Ginnifer Goodwin); a potential fourth; a growing brood of eight children; his oldest, Sarah (Amanda Seyfried) in open rebellion; a struggling gaming business; and his Home Plus superstores left vulnerable. And he now seeks to partner with a Native American tribe on a Mormon-friendly casino just across the Idaho border; his imprisoned father-in-law the "Prophet" Roman Grant (Harry Dean Stanton) plots against him; Roman's twisted son Alby (Matt Ross) asserts his own lust for power; and Bill's parents continue their murderous feud. Finally, there's the nationwide crackdown on polygamy! Who knew so much drama could be packed into one season. Keep up with the Henricksons -- and their secrets -- in all 10 of these episodes, which aired in 2009 on cable network HBO.
