The book tells the story of Joe Rapps, a director and cameraman who slips into the surreal world of Milton Magna, an Oxfordshire village which is based on the real village of Great Milton where de Larrabeiti lived for over thirty years. Rapps is drawn into various conspiracy theories revolving around the "Friends of Diana", a cult which has grown up around the memory of Diana, Princess of Wales, and is determined to avenge her death in a car crash in Paris on 31 August 1997. Although the book is not as explicitly anti-authoritarian as de Larrabeiti's most famous work, "The Borrible Trilogy", its satire of members of the royal family ensure that the book is run-through with the anti-authoritarianism that is present in all of de Larrabeiti's work.
