In Harrogate, a reckless motorcyclist with a long history of violenc puts lives in danger as he desperately tries to outrun the cops, while a trap is set on the A1 by police targetting more county line drug dealers. A night-time sting leads to the arrest of another drugs suspect after a roadside test finds cocaine in his system and a large bag of suspicious white powder inside a shopping bag.

Officers deal with back-to-back accidents, involving a motorcyclist left with life-changing injuries after being hit by a truck while parked in a lay-by, and a lorry driver trapped in his cab with brain injuries. A pensioner struck by a lorry on an industrial estate is left with serious injuries and taken to hospital, while police try to discover what happened and who was at fault.
