Big Love is back!

And while some things change, others stay the same. In a clip from Sunday's season 4 premiere (9 p.m. EST) on HBO, Nicki (Chloƫ Sevigny) is still caught up in the politics of her compound past and her sister wives, Barb (Jeanne Tripplehorn) and Margene (Ginnifer Goodwin), remain skeptical. But she's back in the good graces of their husband Bill (Bill Paxton), who is determined to defend his family. Also this season, the Henricksons are opening a family-friendly casino, eldest daughter Sarah (Amanda Seyfried) is set to be married to her older boyfriend Scott and Margene is pursuing a career on a home shopping network. And with Bill running for office and a power struggle at Juniper Creek, there are sure to be many more twists and turns as the season of polygamist drama unfolds.
