The Thin Blue Line Episode Rating Graph

Goody buys Fowler a puncture repair kit and Habib some lingerie, but accidentally gives them the wrong presents, and matters are made more complicated when Dawkins believes the lingerie is a gift for her from Fowler.

Constable Habib finds her younger sister holding drugs during a drug raid in a rave club, and hides the drugs to protect her, but she is discovered and charged for withholding evidence. Fowler, unhappy with the injustice, does his best to protect Habib.

Inspector Fowler proposes to Sergeant Dawkins so as to help his chances for promotion, but his lack of sensitivity during the proposal prompts her to leave him instead. Fowler tries to find a new woman, but loses his interest when he hears that Dawkins is now with someone called "Toby."

Habib falls for a fireman named Gary, much to Goody's jealousy, while Fowler finds himself pestered frequently by a man who claims to have committed impossible, solved or extremely historical crimes, much to DI Grim's amusement, until a terrorist begins making threats that cause Special Branch to become involved.

Sergeant Dawkins leaves for a break with some nature-loving activists, but during this time, they get into a feud with the police for their extreme methods, forcing Dawkins to choose between their arrogant leader, Stallion, or Fowler.

It is the tenth anniversary of Fowler and Dawkins' relationship, but Fowler manages to forget, being instead more concerned with the Queen's Official Birthday.

Dawkins discovers circumstantial evidence of a domestically abused wife, Grim applies to join the Todgers, and Mayoress Christabel Wickham informs Fowler of the presence of an illegal immigrant in Gasforth. Fowler apparently solves the crimes, but soon realises that they seemed a little too easy.

Fowler receives a letter from the BBC, who then come and make a fly on the wall documentary about Gasforth Police Station. Unfortunately, Grim convinces the officers, sans Fowler, that they are all going to become international television stars, prompting them all to undergo many changes to look "nice for the telly" and end up making fools of themselves in front of the cameramen until a farmer enters the station with a gun.
