However, shortly after her release, members of her own family begin to die mysteriously. Suspecting that a revenge attack may be on the cards, DCI Jardine attempts to discover who would want to carry out such attacks.

A string of people are murdered by electrocution. All of these people are in some way connected to with a local (and popular) spiritualist, who claims he can speak with the dead. When the Taggart team disbelieve the man's powers, the clairvoyant gives them frighteningly accurate messages from a man very dear to their hearts--Jim Taggart! Meanwhile, the murders begin to pile up, and Taggart team race to find the murderer, this time aided by Jim Taggart himself.

A delivery van is hijacked and its contents stolen. But there's more going on than meets the eye, and meanwhile, someone's knocking off anyone who knows about the hijack, which doesn't include the police! Once again Robbie's past catches up with him and he comes close to crossing the line.

Jardine and the team investigate the murders of drug dealers in the Glasgow community.
