When a body is found in the basement of a burnt-out factory, Burke realises that his arson case has become much more interesting than originally thought and uses the case to test his officers. While Fraser attempts to identify the dead man, Burke and Ross pressurise their prime suspect - rival factory owner Scott Dewar

The discovery of the body of an underage prostitute causes Ross to go after a long time nemesis with renewed vigour. This decision sets into motion a chain of events which not only puts the Inspectors career in jeopardy but also numerous lives.
