Shell and Denny arrives at Kings Cross in a taxi. After doing a runner without paying their fare, they slip into the shadows and locate Gary, a drug dealer friend of Denny’s. After Shell gives him the big come on, he lets them have the keys to his flat. They repay him by snorting all his cocaine and stealing his money before donning a pair of frightful wigs and heading off to settle some old scores. Sylvia and Bobby Hollamby receive a nightmarish visit from the pair who are high on coke, and hell-bent on revenge.

After reading Shell’s diary, Karen is convinced that the permissiveness of Helen’s lifers’ regime is solely to blame for the escape. However, when the Area team question Helen about the diary, she quite logically points out that the bar of soap, complete with convenient key impressions, that was found in Shell’s cell proves that she had outside help to plan the escape. Now convinced that the diary was a prop to set Helen up as a scapegoat, the Area team send it away for forensic tests, hoping to prove that all of the entries where written by the same pen and on the same day.

Once the Hollambys are in their power, Shell and Denny tie Bobby to a pair before they strip-search Sylvia and force her to dress in a French main’s outfit they found in her laundry basket. After being forced to serve her captors lines of cocaine on a silver platter, Sylvia is locked up in a cupboard. When the gruesome twosome finally tire, they gag Bobby and tie him to the toilet before heading off to bed. After discovering signs that Bobby tried to escape during the night, Shell decides to teach him a lesson. She takes him down to the garage and forces him to climb into one of his own coffins. Sylvia is forced to look on in terror as Shell drenches the coffin in petrol and then sets light to it.

Helen goes to question Shaz and, although she refuses to tell her anything, Shaz does let slip that Denny and Shell are planning a surprise visit to “an old friend”. When she hears from Karen that Sylvia hasn’t turned up for her shift, Helen becomes convinced that Shell and Denny have decided to settle a few old scores. Having been alerted by Helen, the police arrive at the Hollambys’ in the nick of time. Although they save Bobby, they aren’t quick enough to catch Shell and Denny who make their escape in Bobby’s hearse. Later, Crystal receives the shock of her life when she opens her front door to find Shell and Denny standing there. Reluctantly, she allows them to stay the night, but Shell is as vindictive as ever and repays the favour by planting drugs and then tipping off the police before she and Denny leave the next morning.

As ‘Barbara Hunt’ and ‘Nicola Wade’ catch a plane to the Costa del Sol, Stubberfield is informed that Chris, the documentary soundman, has been charged with aiding and abetting the escape. The Area team have also come to the conclusion that Stubberfield was the one ultimately at fault and he is asked to tender his resignation immediately.
