The show is centered on the Walker family, an American family of Irish and Jewish heritages. Some of the family members are involved in the family owned business running Ojai Food Co, a produce distributor. Most of the action is set in the Greater Los Angeles area. The family home is located in Pasadena, California. The main branches of the Walker family tree included father William (deceased), mother Nora, and their five grown children - Sarah, Kitty, Tommy, Kevin, and Justin. Nora's brother, Saul Holdend helps run the Walker family business and is involved in most of the family's affairs.
