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.

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.

Grim and Boyle enlist the help of Fowler and his officers to search the home of a suspected drug-dealer, and Goody finds the drugs in the kitchen. But the too-obvious location, Boyle's discretion and Grim's comfortableness lead Fowler to believe something is going on behind the arrest.

Fowler receives a letter from the BBC, who then come and make a fly on the wall documentary about Gasforth Police Station.
