Nothing is what it seems behind the well-trimmed hedges of the picturesque cottages in the idyllic English county of Midsomer. Beneath the tranquil surface of sleepy village life exist dark secrets, scandals and downright evil. John Nettles stars as the humorous, thoughtful and methodical Detective Chief Inspector Barnaby. Barnaby's favourite Aunt, Alice, is recuperating at the Lawnside Rest Home when one of her fellow residents dies. There don't seem to be any suspicious circumstances and it is assumed to be just a case of old age. Aunt Alice, however, is not so sure. Alice complains of hearing footsteps in the corridor in the dead of night and claims to have spotted a stranger sneaking around the place. When another resident is found dead followed by another, Barnaby and Troy take notice and set out to uncover the truth.
