Stan Butler is a public transit bus driver with the Town and District Bus Co. in suburban London. He is paired with his best friend Jack Harper as his conductor, they partners in crime in the pursuit of the opposite sex which is usually foremost on their minds. They also treat their bus like their own personal service, which is much to the exasperation of their bumbling inspector, Mr. Blake, more commonly referred to as Blakey. Stan still lives at "home" with his Mum, his plain Jane sister Olive who has no discernible skill at anything whatsoever, and Olive's lazy and stingy husband Arthur. With all Stan's overtime due to a labor shortage at the company, the Butlers have been on a spending spree of late for major items for the household. That spending spree comes to an abrupt end when Blakey implements a new directive to fill those job vacancies which kiboshes Stan's overtime: hire female drivers, driving which has up to this point been the sole domain of the male gender. What is worse for Stan and Jack is that most of the new female hires proverbially possess excess testosterone. Olive ends up playing an important role in especially Stan's need to maintain that overtime. So Stan and Jack embark on a mission to put the new female hires in a bad light so that they will ultimately be let go.—Huggo
