A British sitcom which focuses on working-class life. The bus driver Stanley "Stan" Butler is a somewhat frustrated bachelor, forced to share a house with his overly conservative and financially needy mother Mabel, his overweight sister Olive, and his stuck-up brother-in-law Arthur Rudge. So he tries to have some fun while working by flirting with attractive women, messing with the people which he dislikes, and scheming for extra money. His best friend is the conductor and shop steward Jack Harper, though he is not above seducing Stan's girlfriends or backstabbing Stan for personal gain. Their main foe is the bus depot's inspector Cyril "Blakey" Blake, a frustrated bureaucrat who keeps trying to have the men either disciplined by their superiors or outright fired. Since Blakey is overzealous in trying to enforce the rules, and he is not particularly trusted by anyone else, his efforts are doomed to failure.
