Merton is unimpressed by Rob's methods of dealing with a blackmailer who begins terrorising the owner of a refuge, one of Liz's patients - and Alf Ventress' goddaughter. Meanwhile, Vernon, Bernie and David embark on a venture in the world of publishing with a famous publisher on the verge of bankruptcy.

A ruthless loan shark forces a desperate family man trying to pay for his daughter's wedding into engineering a robbery at the warehouse where he works. Unable to pay the loan and fearful for his life, he confides in Blaketon, leaving the former cop in a difficult position. If he passes on the information to Rob, he'll either destroy a family or put a man's life in grave danger. Meanwhile, David causes all manner of trouble for the locals when he takes up photography as a hobby and catches the villagers in a compromising position.
