The hunt for a serial arsonist that is torching condemned buildings intensifies when a Private Investigator, who is an ex-cop and an old friend of Hooker's, is murdered. Certain that the man was on the verge of finding out who is behind the attacks, Hooker and Romano work with his daughter, who is also a PI, to bring the arsonist to justice...

Responding to the alert of an armed super-market robbery, Romano and another Officer are wounded when one of the robbers opens fire at them. Romano blames a female Officer on the scene, who he believes to be guilty of cowardice in stopping the shooting, but with contradicting accounts of just what happened in the incident, Hooker angers Romano and several Officers when he announces he is to act as defence for the Officer in the upcoming trial. The move jeopardises both Hooker and Romano's partnership and their friendship, and the fact that the Officer had previously been brought up on a similar charge does not help her case; but was she actually the one to blame on this occasion?...
