Brothers & Sisters" heads into its fifth season as executive producers Ken Olin, Greg Berlanti and David Marshall Grant continue to follow the California-based Walker family through the complicated maze of American life today. 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, illness, politics, divorce, infidelity, addiction, arrest, 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 and lies of their larger-than-life family patriarch, William Walker.
