The Masterpiece - S2.E14

Chicago, December 1931. With Al Capone in prison, the bootlegging part of his empire was split in 2. One of Capone's lieutenants, Mayer Wartel, acquired the speakeasies; another lieutenant, Karl Positan, acquired the breweries and distilleries. In an attempt to take over the entire operation, Positan withholds his whiskey and beer; the number of speaks flourishing drops to an all-time Prohibition low. Eliot Ness and his men keep an eye on the situation.

Nitti's plenty sore.
