When gangsters invade and shoot up a speakeasy on the outskirts of Chicago, Ness thinks Frank Nitti may be trying to get rid of some of his competition. When one of Nitti's joints is bombed soon after, the authorities are worried that a massive gang war may erupt. The problem for Nitti is that the out-of-town clubs are getting quality booze smuggled in from Canada and its drawing away his well-heeled customers. He learns from one of the roadhouse managers that Parnise Surigao has been importing the liquor but he won't reveal where or how he's doing it. When Nitti takes one of the smugglers hostage and learns where Surigao is storing his liquor, he decides to get his hands on it.
