Eliot Ness and his men are having success shutting down the narcotics trade in Chicago thanks to a series of anonymous telephone tips. Ness manages to trace the call to a phone booth and identify the caller as Nick Dulov, owner of the Windy City cab company. Dulov has stolen Nitti's 15 kilo shipment of heroin and then gives it back to him - with a proposition that they go into the narcotics distribution business together.

Always looking to expand their area of control, the mob is now out to get control of the bakery industry. Eliot Ness is in New York to testify at a trial and the local US Attorney asks him to stay on to help with the problem. Under the control of the Syndicate, Louis 'Lepke' Buchalter tasks Bryan "Bull" Hanlon to gain control of the industry by establishing a truckers association to get control of deliveries. Hanlon's inclination is to start with small bakers and slowly move up but under orders, he goes after the largest baker in the industry, Adam Stone.
