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.

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.
