When a farmer is assaulted, Nick is forced to investigate the possibility that one of his oldest friends from London may be responsible, who also happens to be a reformed criminal. Meanwhile, Aidensfield is hosting a cricket match against Whitby, and as usual, Greengrass is taking bets on the outcome of the game, but he's not the only one. Elsewhere, Nick's mother Ruby returns to Aidensfield and tries to rekindle her brief romance with Blaketon, much to his dismay!

A new arrival and the possibility of a merger heralds big changes for the Ashfordly station as Blaketon is replaced by Inspector Barry. However, the team must adapt to change as they attempt to track down a mysterious man in a Jaguar, who is attacking local youngsters, whilst Blaketon ponders retirement when he receives a tempting job offer at a security firm. Meanwhile, Greengrass ends up in hospital after agreeing to put a bet on for a friend and decides to set up home on the hospital ward as danger awaits him on the outside.
