When his father is murdered, erstwhile conman Nick Darrow asks the cops if he can go undercover to find the killers, and maybe even stop a crime ring that has been plaguing the police. The sister of another innocent victim joins him as they infiltrate the syndicate. Any wrong move could lead to instant death.
