Once again, FBI Agent Katherine Katt and Detective Mickey (Mouse) James are thrown together in a battle of wits and wills as a city's lawmakers are being murdered one at a time. As a matter of duty, Katt is called in to figure out who could do such a thing. James' purpose is more personal. His cousin is the only survivor and he's there to make sure the killer doesn't finish what he started. In order to succeed, Katt and Mouse seek the help of someone even more dangerous than the person they are hunting. What they don't know is whether he's there to help or is he just using them to finish off what he already started.
