During a busy spring bank holiday, the traffic cops deal with the effects of drink and drugs. A dangerous drunk, unlicensed and uninsured driver leads officers on a 20-minute chase through busy areas, while a suspected drugged driver runs across a supermarket car park to avoid arrest. The victims of a hit-and-run incident report a man who denies he was at the wheel.

A police camera alert is issued for a wanted criminal and after a 130mph pursuit along the M1, officers from two forces manage to stop a 20-year-old driver and his passengers, one of whom is just 17, Just outside Matlock, officers are called to an incident involving three motorcyclists who have been hit head-on by a car being driven by a young driver, who is arrested on suspicion of dangerous and drugged driving.
