Chicago, 1931. On the Southside, on a dead end street, there is a junkyard-- but it's really a front for a narcotics empire, run by gangster Victor Salazar. Ness and his men are on the case; they keep intercepting his trucks, carrying shipments of narcotics. Barney Howe tells his boss Salazar that his problem is the operation's too spread out; but one big shipment will give him the Northside, too-- Barney says he will ""put Chicago in his pocket."" Late at night, they get a call from a hood named Kierson who has info in his briefcase: the time and route of a $2-million commercial shipment of morphine crystals to a medical research center; he's to meet them at the corner of Mohawk and 23rd in 10 minutes.
