Number 3 Gang - four completely different dustbin men (or how they prefer to be called refuse collectors), who have one thing in common - they devote their time to skiving and scheming to earn some money or at least drive their depot inspector mad.
PC Penrose joins the local police force in small town and gets under wings of Sergeant Flagg, who shows him the ropes. Soon young and naive Penrose learns that his job is more complicated than he thought.
