Harry Grout, Slade Prison's resident bigwig, is arranging for the escape of fellow prisoner, Oakes, under the guise of a celebrities vs convicts morale-boosting football match.

Fletcher and Godber, nearing the end of their respective sentences, are horrified to find themselves roped in on the scheme - try as they might, Grouty's just not a man you can say 'no' to.

As the villainous plot unfolds, the pair find themselves even deeper in it than they'd feared, and are soon outside the prison walls themselves. It may be something they've dreamed of for years, but so close to their release dates, the duo are far more concerned about suffering even longer sentences for escaping.

Splitting from Oakes's getaway, Fletch and Godber are in a race against time to get themselves back across country undetected, and back inside the prison walls without being caught. Whoever heard of convicts wanting to break into a prison?
