It's Saturday afternoon and Fletcher looks forward to a quiet read. Everyone else seems to have other ideas about how Fletcher should be spending his time.

Fletcher is having a spell in the prison hospital with a broken ankle. He's sharing a ward with old Blanco, who tells him that another inmate has swindled him out of his belongings in a crooked card game. Fletcher hatches a plan to recover Blanco's belongings and to take revenge on the culprit.

Godber takes up boxing and wins a place in the prison championship, so Fletcher sees a chance for a bit of a flutter. Then Harry Grout takes an interest and insists that the fight is 'fixed'. When one of Grout's rivals takes a similar interest in Godber's opponent, it looks as if nobody can win. Fletcher, however, has other ideas.
