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.

Bobby saves Peter from being hit by a falling ladder and in return the older Brady promises to become Bobby's slave.

Mike's horoscope predicts that a strange woman will come into his life.

The quarterback of a rival football team takes a sudden interest in Marcia.

Jan considers herself a loser when her latest interest, tap dancing, drives the whole family crazy.
