Premise: Here's the story ... of a man named Brady, an architect widower with three sons: oldest Greg, middle son Peter and youngest Bobby. He meets and marries Carol, with three daughters of her own: oldest Marcia, middle girl Jan and little one Cindy. Tending to them is a wacky maid named Alice. They all live in a four-bedroom, two-bathroom house in the Los Angeles suburbs. The story lines deal with boy problems, sharing bathrooms, lost hamsters, the occasional football to the nose, and attempts at pop music stardom.
