The demand for real beer goes unabated and Charlie Zenko tries to consolidate his control of the North side of Chicago. He arranges for brewmaster Franz Koenig to get a visit from Eliot Ness. At his trial, Koenig is saved when a stranger, Leo Mencken, provides him with the alibi he needs. Soon Koenig and Mencken are partners and are using Mencken's unique way of temporarily masking the re-alcoholization of the beer they produce. Charlie Zenko is not pleased that his competition is back on the street but has the good sense to check with New York mobster Joe Kulak, who confirms that Mencken is working for him. When they finally meet, Charlie Zenko is shocked to see just who Leo Mencken really is.
