"The true story of FBI man Eliot Ness's savage war on the notorious mobsters Al Capone left behind!"

Joe Lassiter is the greatest inside man in the bootlegging racket. He and his sidekick, Nick Karabinos, have just arrived in Chicago by train; Lassiter traveled 1,000 miles because of a 250 grand deal: build a Ness-proof brewery. At the closed Bell Club (which Ness took apart last week), Lassiter meets with bootleg czar Louis Tully and his associates.
