It's Dorset wedding bells for Keith Chitty and best man Gerry O'Dowd decides to enter into the swing of things. Gerry's taking no chances and neither is Sgt. Rockliffe. When their paths cross back in town they both get more than they bargained for.

Members of Rockliffe's crime squad make hasty character assessments. Wayne is an animal, Chris is a charmer. Both judgments have to be revised on closer inspection.

Why are the officers of Church Street police station tuning in to a local radio station? And why does Rockliffe allow himself to be involved in a situation which causes so much disapproval from on high?

It is not a crime to photograph police activity, but when it happens during an investigation into serious assaults on women Sgt. Rockliffe is suspicious. What he discovers puts him into the most disagreeable situation of his career.

Rockliffe's team is in hospital. They are watching for someone who is frightening the nurses. But when a nurse is hurt in their full view, they realise they have a different and more urgent situation on their hands.

It is a night of routine surveillance for the Crime Squad. All is quiet, but not for long. Sgt. Rockliffe and his team soon find themselves in areas of enquiry that are foreign to them and where there are choices to be made between public justice and private revenge.

Acting on information received seems more important to Rockliffe than taking notice of a memo from the Chief Superintendent. Embarrassment results. Except for Georgiou, who volunteers for a very risky adventure.

The two married members of Rockliffe's team have a dinner engagement, but the demands of duty put paid to their plans. An entirely different night out on the town is arranged for them - spiced with an element of risk.

Rockliffe thinks WPC Walsh is too preoccupied with the problems of a homeless family. But he is not entirely impartial himself when it comes to associating with an attractive titled woman who seems to be unattached.

Before Rockliffe and his team can start to look for three villains who got away they must find out who they were. It's a challenge that exercises all their ingenuity and certain members of the team have other things on their minds: three of them have selection boards for the Detective Training School.
