Architect Mike Brady marries beautiful young Carol, who has three girls to care for. Likewise, Mike's previous wife's death has left him to raise his three boys all alone. In no time this amalgam becomes the ideal average American middle class family. Of course, raising such a large family isn't easy, so live-in housekeeper Alice Nelson is always there to lend a hand.

The trials and tribulations of bus driver Stan and his conductor Jack unfold in this weekly comedy. The bain of their working life is Inspector Blake who'll do anything to make their lives a misery... and does. Stan and Jack are a couple of "jack-the-lads" who are not averse to clocking a bit of crumpet here and there, but "Blakey" is constantly dampening their ardor.
