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.
Marcia's new part-time job at an ice cream parlor causes problems at home and with her boyfriend.
Bobby saves Peter from being hit by a falling ladder and in return the older Brady promises to become Bobby's slave.
The quarterback of a rival football team takes a sudden interest in Marcia.
Greg gets his driver's license and his first vehicle with the help of his fast-talking buddy. But the car turns out to be beat-up and there is no restoring it.
