In this episode, Fletcher finds himself in trouble when two rival prisoners decide to fix a boxing match, leaving him at risk of the wrath of one of them for helping the other.
While Godber is out getting training, Fletcher is summoned to meet with Harry Grout, who lives a more lavish lifestyle due to his criminal reputation.
On the night of the match, Fletcher informs Godber that apart from himself, either he or his opponent will face trouble if one of them takes a dive, leading to them devising a plan.
When Fletcher reunites with Godber in his cell, he reveals that neither Grout or Moffatt have made a gains or losses, as all the bets they had arranged were voided by the result of the match.
However, Fletcher admits he made a bet on the match ending in a draw and came off well as a result, and offers Godber his favourite chocolate bar to celebrate.
