Greg Warner is a motion picture executive, and Kim Warner is a stay-at-home mother to Sammy and, later, Emily. Kim's sister, Christine Hughes, and Christine's husband, Jimmy Hughes, along with their two sons, Dominic and Logan, live in the Warners' guest house.

Much of the show's humor comes from the fact that all four adult leads are largely stock characters. Greg is the stereotypical "nice guy," constantly being henpecked by his high-strung wife. Both contrast to the decidedly working-class and less restrained Hugheses, with Jimmy having the personality of an oaf and Christine being somewhat more crass.
