A body in the river is all in a day's work for Detective Inspector Peter Johns and his Sergeant, Paul Godwin. But things become personal when Peter's son is detained for suspected child abduction and Paul recognises their key witness as a close childhood friend. The detectives soon discover that they have more in common than they realised and it becomes difficult to keep work and family life separated when difficulties arise in the investigation of the body in the river. It looks like suicide. But is something more sinister in play?
