Think having three wives is a dream come true? Meet Bill Henrickson (Bill Paxton), a modern-day Utah polygamist who lives in suburban Salt Lake City with his three wives, seven children, and a mounting avalanche of debt and demands. The owner of a growing chain of home improvement stores, Bill struggles to balance the financial and emotional needs of Barb, Nicki and Margene (Jeanne Tripplehorn, Chloë Sevigny and Ginnifer Goodwin), who live in separate, adjacent houses and take turns sharing their husband each night. While managing the household finances together and routinely sharing "family home nights," they try to keep simmering jealousies in check and their arrangement a secret — polygamy is illegal in Utah and banned by the mainstream Mormon Church. Adding to Bill's woes are a series of crises affecting his parents (Bruce Dern and Grace Zabriskie), who live on a fundamentalist compound in rural Utah, and his ruthless father-in-law, Roman (Harry Dean Stanton), the powerful head of the polygamist commune where his parents live. Bold, funny and wholly original, Big Love explores the evolving institution of marriage through a typical atypical family.
