Dr Jonathan Paige and Sgt Diamond are nearby when a gas explosion happens in the middle of Warwickshire. They're on their war to see Inspector Gillian Cramer pick up an award for bravery. After being shot she's back on duty but tender things remain unsaid between Gillian and Jonathan. How long will this last and are they right for each other? The new cockney forensics man, Matt Gregory, is on the prowl. The main case centres around the explosion and Clive Daniels, a sinister computer nerd. Paige and Diamond are on their way to DI Cramer's commendation ceremony in London when an explosion disrupts their journey. A forensic scientist is called in to investigate, and tensions arise between him and Paige, although it soon becomes clear that a computer is controlling events in Warwickshire.
