CBS has been given the contract to guard a building site - a derelict church which is due to be demolished and replaced with luxury flats by a local builder, Donald Bannerman. During a violent thunderstorm, there is an earth movement and some ancient statues are uncovered. Dr Freda Butler, an archeologist at the university, insists on being given access, saying that the statues date back to the time when there was a Cistercian monastery on the site. Bannerman refuses, but Ken decides to let her have a quick look at the statues while Bannerman isn't there.

During the night, one of Bannerman's JCBs is sabotaged when sand is poured in the fuel tank. Freda and her students are blamed. Bannerman threatens to hand over the security contract for guarding all his sites to Jack Fentiman, one of Harry's rivals. Harry wants to sack Frank, the security guard who was on duty at the site. However Ken feels sorry for Frank, who is the rather simple brother of another CBS guard, Bertie, and insists on

Ken is in the process of moving into a derelict house in the village of Upper Ridley. He has arranged with the owner that he will live there rent-free in exchange for renovating it.

John Pritchard approaches Harry and wants CBS to provide security guards for the launch of his new health club. He wants the guards to wear tracksuits, which he will provide, so they will blend in with the punters. Harry promotes Rocky to ""executive"" and gives him the task of employing suitable college students: no mean feat when all the tracksuits are extra small! One of the students, Vicky ""Mouthpiece"", gives Rocky a hard time, quoting the Factory and Sex Discrimination Acts as she attempts to do as little work as possible. However Rocky soon puts her in her place.

John Dewar, the owner of a dairy, suspects that his wife, Melissa, may be having an affair and asks Ken to investigate. Ken is reluctant to do so, firstly because he wants to get on with moving into his new house and secondly because he hates w

Ken makes a start on renovating Orchard Cottage. Pam Strong, one of his neighbours and the widow of a fireman, tentatively asks him for help because her son John has changed suddenly: he has dropped out of college, become sullen and uncommunicative and has started locking himself in his room. She also suspects that he may be stealing from her. Something is wrong - could it be drugs, Pam wonders. John has become friendly with another teenager called Mark who rents room at a nearby farm.

Mark and John steal a car and drive around, terrifying the locals. The car hits a man and woman on a bridge, but Mark drives on, dumping the car in a quarry and swearing John to silence. But John later recognises the man that was knocked down as a local doctor, James Harlon. It was Harlon who got John his part-time job as a porter at the hospital.

Ken visits Dr Harlon, not realising that connection with John and the accident. Dr Harlon describes John as quiet and a bit of a loner, but not the sort to be

While Ken helps the traders, Harry and Alex try to win a big security contract and find themselves at odds with their partner.
