Overview: 1932. Chicago is a thirsty town, consuming 86,000 gallons of booze a day; that's 32-million gallons a year. Almost all this booze is beer and rotgut, but 1% is the finest Canadian scotch. Nitti's boys, armed with tommy guns, shoot up a rival speak, the Blue Lion, that's serving the Canadian scotch. Ness and his men investigate; 2 people dead, 3 critically injured.
