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.

The new family dentist becomes the subject of Marcia's daydreams when she misinterprets his interest in her.

Bobby becomes very unpopular when he decides to be the best safety monitor at school.

Greg has a near accident on the freeway and his parents deny him car privileges for a week.

Greg and Marcia are left in charge of the rest of the clan when Mike and Carol go out for the evening.
