Times are tough for everyone these days, including home-improvement store owner Bill Henrickson and his three wives. In the face of a flat do-it-yourself market and a crackdown on polygamists around the country, Bill wants to protect his growing family and his chain of Home Plus superstores by diversifying his business operations and building neighborhood goodwill. And as if his life wasn't complicated enough already, he wants to take a fourth wife who can produce more children.

The drama series Big Love kicks off its ten-episode third season with the episode entitled Block Party, debuting Sunday, January. 18 (9:00-10:00 p.m. ET/PT), exclusively on HBO, followed by other episodes on subsequent Sundays at the same time.

Big Love tells the story of Salt Lake City native Bill Henrickson, who balances the needs of his three wives - Barb, Nicki and Margene - their eight kids, three houses and his home improvement stores. Bill Paxton, Jeanne Tripplehorn, Chloë Sevigny, Ginnifer Goodwin and Harry Dean Stanton star in the series, which is executive produced by Playtone's Tom Hanks and Gary Goetzman, series creators Mark V. Olsen & Will Scheffer, and David Knoller.

Fresh from a bitter, albeit successful, battle to acquire a gaming-machine business, Bill Henrickson now faces a new array of personal and professional challenges. Over the course of season three of Big Love, he will try to convince a Native American tribe to partner on a Mormon-friendly casino; woo a fourth-wife prospect through unorthodox group-dating rituals; face unexpected repercussions from the imprisonment of "prophet" Roman Grant and the rise of his treacherous son Alby; deal with escalating hostilities involving mother Lois, father Frank, brother Joey and sister-in-law Wanda; and navigate crises involving his children Sarah, Ben and Tancy.

Other returning series regulars on the third season of Big Love include Shawn Doyle, Mireille Enos, Joel McKinnon Miller, Matt Ross, Amanda Seyfried, Douglas Smith, Melora Walters and Grace Zabriskie. Also appearing are Daveigh Chase, Bruce Dern, Branka Katic, Tina Majorino, Mary Kay Place and Jolean Wejbe.
