The Untouchables S03E17 - Takeover

The demand for real beer goes unabated and Charlie Zenko tries to consolidate his control of the North side of Chicago. He arranges for brew master Franz Koenig to get a visit from Eliot Ness. At his trial however, 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.
