The Troubleshooter - S3.E1

In the summer of 1934, a new gambling device was sweeping the nation: the punchboards. Even though they were nickel-and-dime games, it added up-- they made more money for the mob than the numbers racket. After Ness and his men smash some of the punchboard manufacturing sites, the 5 members of the syndicate running the punchboards hold a meet at a building by the freight yards: the top mobsters from Chicago (Jake ""Joe"" Petrie), Cincinnati, St. Louis, Detroit and New York (Max Riegel).

Petrie says he can sum up all their problems in 2 words: Eliot Ness.
