It's about a serial killer with terminal cancer who leaves numbered cards on his victim's bodies, a girl who falls in love with him, a loser cabbie who becomes the prime suspect, an old asshole police sergeant, and a radio reporter who takes the law into his own hands.

A detective becomes obsessed with bringing a man to justice, whom he is sure is a serial killer and the murderer of a woman with which both men were involved. However, the supposed killer may be as much a victim as the murdered people.
