Fletch is almost tempted off the straight and narrow on the day Ingrid is to marry Godber. He has a change of heart before it's too late but almost gets into trouble with a walkie talkie. Godber married Ingrid with Fletch giving away the bride and acting as best man.

Fletch has now reached the end of his stay in Prison and says his goodbyes to McLaren. On the train journey home Fletch bumps into Mackay and an old friend. His old friend makes an early attempt to tempt him from the straight and narrow but it's Mackay who almost commits a crime.

As hotel porter, Fletch recognises an unscrupulous guest and suspects a scam.

Fletch visits his probation officer and reveals that his wife, Isobel, has left him for someone called Reg Jessop who owns a cardboard box factory. Fletch doesn't seem too concerned about getting a job and the reason is a legacy from a previous crime which he attempts to dig up by stealing Godber's lorry and driving off to the site where the loot was buried. He is out of luck, however, when he discovers a housing development has been built on the field.

Fletch's probation officer sets him up with a job as a night porter. Fletch is nervous about his first ever job and can't face it but Godber and Ingrid make sure he turns up.

Fletch is diverted from his own problems when he comes across a young punk girl and tries to set her on the straight and narrow.
