Boardwalk Empire is a period drama focusing on Enoch "Nucky" Thompson (based on the historical Enoch L. Johnson), a political figure who rose to prominence and controlled Atlantic City, New Jersey, during the Prohibition period of the 1920s and 1930s. Nucky interacts with several historical figures in both his personal and political life, including mobsters, politicians, government agents, and the common folk who look up to him. The federal government also takes an interest in the bootlegging and other illegal activities in the area, sending agents to investigate possible mob connections but also looking at Nucky's lifestyle—expensive and lavish for a county political figure.
Eli confronts Nucky after Willie makes an unpopular decision. Margaret has a surprise encounter at her job on Wall Street. Joe Masseria orders Lucky Luciano to return to Tampa and deal with Vincenzo Petrucelli. Gillian goes cold turkey, with Roy Phillips’ help. Still seething over his brother’s death, Al Capone tries to get Johnny Torrio to turn on rival gangster Dean O’Banion. As Chalky White and Daughter Maitland’s relationship deepens, Valentin Narcisse exerts his control over Dunn Purnsley and the Northside.
