Otto Frick is a drug dealer with a traveling group of distributors. Ness and his men trace his supply chain to a book shop whose owner regularly visits the German Consulate in New York. Ness soon realizes that the Nazis are supplying Frick and that one of its agents, Walter Messlinger, is the point of contact. What Ness doesn't yet realize is that Messlinger wants Frick's experience as a hood to start using Nazi strong-arm tactics against local citizens.

When Al Capone is convicted of tax evasion, he's sentenced to 11 years and sent to the federal penitentiary in Atlanta. Capone's farewell is something normally reserved for more honest citizens leading Eliot Ness to go to Washington and propose the construction of Alcatraz prison. In Atlanta, Capone has a pretty good thing going, including guards who make life pretty easy for him in exchange for cash. When it becomes apparent that he too will be transferred to the new prison, Capone uses a cell mate's knowledge of the railroad route to plan his escape.
