Season 3 begins with Tara (Toni Collette) returning to the family’s Labor Day barbecue, after a transition to Buck leads her on an unexpected mission. Kate (Brie Larson) is trying desperately to plan the next phase of her life, one that does not include college or living with her very pregnant Aunt Charmaine (Rosemarie Dewitt), who, in her own way, avoids committing to Neil (Patton Oswalt). Meanwhile, student filmmakers Marshall (Keir Gilchrist) and Lionel Trane (Michael Willett) make their first commitment together when they purchase a new video camera for film class. All the college talk makes Tara realize how badly she wants to finish the last few credits of her own degree, and so, with the help of Ted Mayo (Michael Hitchcock), Tara enrolls in a few classes, including a psychology course taught by the charismatic Dr. Jack Hattaras (Eddie Izzard). But Max (John Corbett) is fearful that the stress of college will cause Tara to transition…or worse.
