Caught in the middle of two tribes, it's Bess who must keep juggling the fallout - on her adoptive and overbearing mother, Margaret, her loving but slightly spoiled husband, Danny, her twins, Oscar and Edwina, not to mention the Wheelers, her newly found - and delightfully bogan - family.

Two years have passed since Bess, an upper middle class doctor, discovered she was adopted and found her drag racing, biological parents living in the outer suburbs. With her two families, the Brights and the Wheelers, each now facing a brand new set of challenges - moving houses, illness and injuries, relationships ending and beginning - Bess struggles to manage her families living at opposing ends of the freeway, with varying levels of success.
