The death of Albie Kinsella's father has a disturbing effect on him and soon after, he kills an Asian newsagent. With all the hallmarks of a racist attack, the police fail to make any headway. Meanwhile, criminal psychologist Fitz is trying to put some order into his personal life and, after sorting out his differences with DCI Bilborough, becomes embroiled in the case.

Albie is intent on killing the same number of victims as died in the Hillsborough football tragedy, and targets a freelance female reporter. DS Beck stumbles upon him, but makes a tragic misjudgement, leaving Albie free to stab DCI Bilborough to death. It looks like criminal psychologist Fitz will be needed to resolve the situation before any more deaths occur.

Following the murder of DCI Bilborough, the hunt is on for Albie. DCI Wise takes over the investigation and criminal psychologist Fitz is brought in to defuse a potentially fatal and explosive situation.

Fanatical religious group leader Kenneth Trant discovers that his girlfriend Joanna is still alive and turns his attention to Dean, whom he trusted to dispose of her body. With Joanna hospitalised, DS Beck extracts a confession from Dean while criminal psychologist Fitz tries to get at the truth. He persuades DCI Wise to see Dean in his cell, but fears it may be too late.

The case ends with a final showdown in the group's church, where things reach a destructive conclusion.
