New York, 1933. Racketeers are poking their greasy fists into every corner of the nation's business. The Fulton fish market in New York supplies fish on the East Coast to as far west as the Mississippi; they supply 700-million pounds of fish a year, worth $200-million. When Captain Joe McGonigle, owner of the fishing boat the Margie Mac, won't pay protection money, 2 of Frank Mercouris' hoods, Lenny Shore and Swede Kelso, drown his deck hand, and it makes the newspapers; it's only the beginning of trouble with the Syndicate moving in-- and so Eliot Ness and his men fly to New York.
