When a pirate radio station called "Radio North" begins broadcasting in Aidensfield, Nick locks horns with Joe Norton's gang once again as the team tackle a case of drug smuggling. However, Joe Norton is a changed man, and when he is tragically killed at the hands of his old gang, Nick cannot help blaming himself and goes undercover as a DJ in Whitby alongside Maggie's brother to bring the gang down. Meanwhile, George, Gina and Blaketon are far from happy when Greengrass begins making homemade whiskey and drives away all the pub's customers.
