The series began with the death of Nora's husband William Walker and follows the discovery that he had a twenty-year affair with Holly Harper and the fact that William and Holly had a child together, Rebecca, that no one knew about.
As well as this central plot bringing the family together, each character must deal with the events of their personal lives.
So far, Odette has only been slated for one episode, but it could be more.

However, on October 25, 2010, it was announced that ABC had picked up four more episodes, bringing the season to 22 episodes in total.
However, his death in the opening episode reveals hidden secrets that serve to test the family and their business 'Ojai Foods' to the limits.
Patricia Wettig stars as Holly Harper; William's longtime mistress and Emily Van Camp appears mid-season as Rebecca Harper; Holly's daughter.
