Friday is working the night watch in the homicide department. A man is shot, and his assailant is loose in the city. The place to start is with the witness who saw the shooting. The dead man is identified, and routine questioning is done with his family. One tip leads to another, and through plodding police work the suspects are tracked down. It might take days, or even weeks and months, but with Friday on the trail the case will be solved. Car theft, burglary, murder, to some crooks one is as good as another.
