Another case for Detective Chief Inspector Barnaby (John Nettles) and Detective Constable Ben Jones (Jason Hughes). Young lovers Simon Bright (Edward Davenport) and Laura Sharp (Lizzy Watts) are kissing in the back seat of a Humber car in a disused aircraft hangar. The next morning, Simon Bright's body is discovered there by Frances Kirby (Felicity Dean) while out for her morning jog. There is no sign of Laura. Barnaby suspects that Simon may have been involved in a suicide pact; however, the evidence tells a different story.
