A new PC called Mike Bradley arrives in Aidensfield and gets off to a rocky start with Blaketon, Ventress and Bellamy. A former Met officer, Mike is cocky, has an eye for the ladies and isn't initially impressed with the old-fashioned ways of Yorkshire. However, he soon discovers that, with Nick Rowan on honeymoon, the village has turned from a peaceful community into a hive of crime and chaos. Mike leaps into action when two armed robbers raid a pipeline compound and take Greengrass and Gina hostage. The stakes are high - and Ashfordly station may never be the same again.

Nick receives a few shocks when he and Jo return from honeymoon to find big changes have occurred in Aidensfield: Blaketon is now retired and running the post office, Mike Bradley is the new village bobby - and he has been promoted to sergeant. In his first case as Ashfordly's leading officer, Nick hunts down a saboteur at the local fair when a showman is left seriously injured. Meanwhile, Greengrass starts a feud with the very unpopular Trevor Lammas when his beloved dog Alfred is poisoned by Trevor's rat, and Ventress, Gina and Bernie also have a score to settle with Lammas
