After being caught and put on trial for hacking credit cards and committing other cyber crimes for personal gain, Nigel Norman Fletcher is sentenced to five years at Wakeley Prison. A few weeks after arriving, Fletcher finds himself sharing his cell with a new prisoner, Joe Lotterby, a senior criminal who knew his grandfather in the past. Meanwhile, Richie Weeks, a hardened criminal who runs an enterprise in the prison, requests that Fletcher use his IT skills to sanitise his record, to ensure his upcoming parole hearing goes without a hitch, though things do not go as smoothly as Fletcher hopes for.
