Special prosecutor John Conroy hopes to combat organized crime in his city, and appoints his cop father Matt as chief investigator. John doesn't understand why Matt is reluctant, but cynical reporter Jerry McKibbon thinks he knows: he's seen Matt with mob lieutenant Harrigan. Jerry's friendship for John is tested by the question of what to do about Matt, and by his attraction to John's girl Amanda. Meanwhile, the threatened racketeers adopt increasingly violent means of defense.—Rod Crawford
