The Untouchables S02E32 - 90-Proof Dame

Nate Kester is a burlesque theatre operator who decides to branch out into the lucrative brandy business. He is producing his own brandy, of very poor quality, and using a fancy French label to try and pass it off as de Bouverais cognac. He realizes that if his scheme is to work, he will have to ensure that the real stuff is unavailable for comparison to the rot gut he will be marketing. He manages to destroy the principal supplier of the real stuff but Etienne de Bouverais himself comes to Chicago to put a new wholesaler in place.
