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 Bradys' neighbors decide to adopt a son and end up with three.

Marcia bets that she can beat Greg's score on the driver's test.

Marcia enters her new dad in a newspaper contest for father of the year, but gets herself grounded for breaking house rules to make the late-night deadline.

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