Another case for Detective Chief Inspector Barnaby (John Nettles) and Detective Constable Ben Jones (Jason Hughes). Local choir member Connor Simpson (Patrick Drury) is found dead in his cottage. A pig's heart and an unsavoury message lie as evidence in his kitchen bin. The Midsomer Worthy choir is competing in the Four Choirs competition and the choir master, Laurence Barker (Peter Capaldi), seems to be taking it all a bit too seriously. Has the rivalry between Aston Wherry and Midsomer Worthy got out of control?
