Underworld U.S.A. (1961, U.S.A.)

Twelve-year-old Tolly Devlin watches four men kill his father.  When he recognises one of them, he swears he’ll get revenge.

When the adult Tolly spots the killer in jail, Vic Farrar, he forces him to name his three accomplices.  They are Gela, a drug boss, labor racketeer Gunther, and Smith, the head of a prostitution ring – all leaders in a crime syndicate run by a man called Connors. Tolly saves Cuddles, a young prostitute who knows too much and has been marked for death by the syndicate.  He then persuades her to talk to the Federal Crime Commission, under the command of Agent Driscoll, while he works to place himself deep inside the Connors’ organisation. On the basis of Cuddles’ testimony, Smith is arrested, shaking up Connors, Gela and Gunther. When Tolly is ordered to raid the commission’s files, he and Driscoll conspire to give Connors phony information … B & White print.
