From creators Mark V. Olsen and Will Scheffer comes Big Love, the story of a Mormon man, Bill Henrickson, living in Salt Lake City with his three wives, three houses, and three families. As if normal family life isn't enough trouble, Bill Henrickson (Bill Paxton, Twister, Thunderbirds) has everything in triple: three wives, three houses, three families. Bill's first and only legal wife is Barb (Jeanne Tripplehorn, Word of Honor) but he also shares the bedroom with middle wife Nicki (Chloe Sevigny, Boys Don't Cry, Dogville) and youngest wife Margene (Ginnifer Goodwin, Ed, Mona Lisa Smile). Bill also has three new adjoining houses, seven kids, and a booming hardware business. The series kicks in as Bill receives troublesome news about his father (Bruce Dern) who lives in a fundamentalist Mormon community in rural Utah.
