Frost investigates an MP's son who is involved in a hit-and-run accident, and a robbery at a private casino, which occur on the same night. He gets a humorless new partner to assist him.

An odd group of animal rights advocates attempting to sabotage a foxhunt includes a working-class teenager, who is murdered. Then another person associated with the anti-hunt protesters is murdered. His investigations take Frost to tea with a local squire, but Supt Mullett is apprehensive lest he upset the gentry.
