Fletcher's doing time for a crime he did commit. He's quick witted and never short of a trick or two to make his life that little bit easier. Lennie Godber's his cellmate who Fletch often teases but also protects in a father-like way. The other two main characters are prison officers; MacKay's a militarily strict type, keen to adhere to the rules, while Mr Barrowclough is almost a complete opposite and easily manipulated by Fletcher.
