The compelling one-hour drama series is about a collection of five enmeshed and somewhat damaged adult siblings and their strong but passionately devoted mother, Nora Walker (Oscar and Emmy Award winner Sally Field). The Walkers' lives have not been without challenge; romance, parenting, divorce, infidelity, addiction, war and even death have pushed each of them to the limit, but they continue to work toward living their lives as individuals, while loving each other unconditionally and trying to maintain some semblance of normalcy after the loss of their larger-than-life family patriarch, William Walker.

Eldest sibling Sarah Whedon (Emmy Award nominee Rachel Griffiths) is a mother of two who left a prestigious corporate job to spend time with her family and run Ojai Foods. After finding the business in ruins, she fights to salvage what's left of her failing marriage and keep Ojai alive. Kevin (Matthew Rhys) is an openly gay lawyer who is cautiously learning about love while keeping the family out of legal trouble. Loyal middle brother Tommy Walker (Balthazar Getty) struggles to provide the emotional support needed by his beautiful wife, Julia (Sarah Jane Morris), and their vulnerable newborn daughter, Elizabeth, while risking everything to open a winery with his father's lifelong mistress, Holly Harper (Patricia Wettig). The baby of the family, Justin (Dave Annable), struggles with war trauma and addiction, while Kitty (Calista Flockhart) hits the campaign trail alongside Republican presidential candidate Senator Robert McCallister (Rob Lowe) - her boss and fiancé.

Saul Holden (Ron Rifkin) is the emotional pillar of the Walker family, struggling to keep Ojai Foods above water while grappling with his own identity. Rebecca (Emily VanCamp) is the illegitimate daughter of William Walker and Holly, who was kept secret for two decades but now seeks a way to fit into this very complex family puzzle.
