Toni Collette is back in her award-winning role as one woman haunted by a cast of characters -- all in her own head -- in the quirky comedy from the mind of writer Diablo Cody. In season three, the battle for the student body begins when Tara goes back to college with all of her alter egos, who quickly turn the school upside down and send her family's complicated, ridiculous life into a tail spin. Eddie Izzard guest stars alongside John Corbett, Rosemarie DeWitt, Brie Larson and Keir Gilchrist.
