A series of seemingly unrelated deaths have occurred around the city. When one is an obvious homicide, Detective Brad Coulter gets the case.

Coulter has barely started investigating when more murders take place. It is clear that the killer not only understands Crime Scene Unit protocols but also has special forces military skills—or training in some sort of Tactical Unit.
During the investigation, Detective Coulter realizes he has a connection to some of the victims. Then the Crime Scene Unit discovers evidence that points to Coulter as the murderer.

Now hunted by his own police service, he has to clear his name.

But the killer has other plans.
