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.
