When the body of a church warden is discovered hanging from the belfry of a village church, DI Tom Janssen and his team must investigate the circumstances that led to his death.

Whilst navigating the fallout from the conclusion of their previous case, the Norfolk CID team is under intense scrutiny with another police force investigating their recent conduct. Some people would like nothing more than to see the team fail. With no clear motive for murder or a reason to take his own life, the team have little to go on.

Meanwhile, a hit and run accident on the Sandringham Estate leaves a pregnant woman in hospital and when the fleeing vehicle is located - abandoned beside a coastal sailing club - the investigating team find more than they bargained for when they look inside.

The hunt is on for a brutal murderer whose motives and goals are unknown, and when other interested parties appear in the area the stakes are raised further. Just who are the hunters, who is watching, and, more importantly, who is the prey?
