 The discovery of a man s naked body in the centre of a crop circle brings UFO fans flocking to Midsomer Parva and the field owned by Sir Harry Chatwyn (John Woodvine). With a hole at the base of the spine, a chunk of hair missing, burn marks and a terrified expression, the corpse bears all the hallmarks of alien abduction. DCI Tom Barnaby (John Nettles) and Sergeant Gavin Troy (Daniel Casey) think stories of flying saucers are a smoke-screen for murder, but extra-terrestrial expert Lloyd Kirby (Kenneth Colley) is convinced otherwise. Lloyd is brought in for questioning but former diplomat Sir Christian Aubrey (Alec McCowen) vouches for his honesty. A post-mortem confirms electrocution, but the victim is a London criminal with no interest in the countryside or aliens. Then the body of a local burglar is found in a crop circle with an identical set of injuries. There are also plenty of earthly goings-on in Midsomer Parva. Sir Harry shares a mistress, doctor s receptionist Sally Boulter (Amanda Mealing), with his daughter Lucy s (Daisy Bates) husband. As a third victim is discovered, Barnaby must discover who is responsible - or if extra-terrestrial powers are truly at work.
