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.

Greg is in hot water after he collects money for rides from his brothers and sisters.

Peter poses as a high-school senior so he can date an older woman.

Greg and his football teammates steal a rival school's mascot.

Marcia's new part-time job at an ice cream parlor causes problems at home and with her boyfriend.
