S2·E21 Apocalypse in Chicago

Robbins defies Ness's orders and investigates Capone's connection to a plan to take over Chicago's railroads.

Pressured by Bureau of Investigation agent E.Q. Johnson, Robbins tries to convince Ness to look into the mysterious murder of two railroad police. Ness refuses, unwilling to get involved with the Bureau or to divert attention from Capone's expansion into Florida.

Ironically, Nitti is also interested in the railroads, and has no more luck convincing Capone to listen. Convinced he is on to a sure-fire scheme, Nitti goes behind Capone's back and teams with a hood named Drenik to pay Lewis, a shady foreman, to run for head of the railroad workers' union.
