DETERMINED TREASURY DEPARTMENT INVESTIGATOR FRANK WARREN GOES AFTER A RUTHLESS MOBSTER KNOWN AS THE BIG FELLOW. WHEN A KEY INFORMANT IS MURDERED, WARREN PURSUES THE GANGSTER ON CHARGES OF TAX EVASION. BUT, WITH A SLICK MOB LAWYER HAMPERING HIM AT EVERY TURN, AND THREATS BEING LOBBED TOWARD WARREN'S WIFE, THE LAWMAN'S CHANCES OF ACHIEVING A CONVICTION ARE SLIM TO NONE. HIS ONLY HOPE IS THAT ONE SYNDICATE BOOKKEEPER WILL HAVE THE COURAGE TO TURN STATE'S EVIDENCE. STARRING GLEN FORD, JAMES WHITMORE, NINA FOCH, BARRY KELLEY.
