This prison comedy is based on the popular British televison series of the same name. Long time Slade prison inmate Fletcher (Ronnie Barker) is ordered by Grouty (Peter Vaughan) to arrange a football match between the prisoners and an all-star celebrity team. Fletcher is unaware that the match is only a diversion so that an escape can take place. When Fletcher and his cell mate Lennie (Richard Beckinsale) stumble on the escape, they are taken along, and find themselves having to break back into prison to avoid getting into trouble.
