Classic BBC comedy series about the inmates of HM Prison Slade. Ronnie Barker leads the cast. ‘I don\'t quite know how to put this, gentlemen, but there is a thief among us.’ Habitual offender Norman Stanley Fletcher (Ronnie Barker) is doing porridge at HM Slade Prison. He whiles away the time sharing his wealth of experience with his fellow inmates, particularly naive, young first-timer Lennie (Richard Beckinsale) whom Fletch takes under his fatherly wing. And he’s always trying to get one over officious prison officer Mr Mackay.
