After Sangers Telephone Service is robbed, CID once again through their weight around at the Ashfordly station as they suspect a local gang are responsible, but Blaketon is convinced worker Tony Mowbray has performed an inside job because he has a history of crime and becomes determined to crack the case before the arrogant detectives and show them that the Ashfordly station are more than capable of fighting crime. Meanwhile, Jo is concerned for one of her pupils, Dennis Cross, who hasn't attended school for days. She and Maggie pay him a home visit and are horrified to find his mother dead - and Dennis nowhere to be seen, whilst Greengrass makes a dodgy deal with a butcher, whose factory is subsequently robbed.

When a tobacco factory is robbed, Blaketon cannot believe his luck when it becomes apparent that Greengrass is somehow connected. Meanwhile, an ex-soldier comes to Aidensfield looking for work. However, he finds his darkest secret coming back to haunt him in the worst possible way when his daughter falls in love with the adoptive son of the B&B owners, and tragedy strikes for Jo when her mother dies.
