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.

Grim and the CID initiate a counter-terrorism operation, Fowler deals with mythomaniacs and Habib becomes attracted to a fireman.

Dawkins is furiously jealous of Fowler's admiration for Habib, albeit as star of his pub quiz team. That worsens when CID needs her as sexy, secret bait for a 'honey trap'.

When Rag Week begins, the Gasforth police deals with students' pranks and bank robbers.

Pestered by his ex-wife, Fowler reluctantly agrees to let his son Bill stay with him and Dawkins for a fortnight. When Dawkins overhears Bill making love to his girlfriend in the bedroom, she becomes envious and attempts to talk Fowler into going to see a sex therapist.

Fowler and Grim clash over their views of handling juvenile troublemakers so they decide to take them on a retreat. Further tension arises when Goody punches a teenage skinhead for racially abusing Habib and is subsequently charged for assault.
