When a woman shoots her husband dead at the Scottish Exhibition Center car park, after discovering that he was having an affair, it appears to be a clear-cut case-until the police realise that he was already dead when he was shot. Taggart and Jardine are brought in. They look at the victim's clients list to discover more.

The discovery of a charred corpse in a disused railway tunnel sets Taggart on the gruesome hunt for a ruthless killer in an investigation with sinister undertones of black magic and voodoo. The wife of an arthritic dentist narrowly escapes a series of murder attempts, adding to a complex case for Taggart and his team.

Taggart investigates a failed rape attempt by a masked attacker. However, his job is complicated when the victim commits suicide and the criminal strikes again, and his attacks soon turn to murder.
