One of HBO's breakthrough series, Boardwalk Empire chronicles the life and times of Enoch "Nucky" Thompson (Golden Globe winner Steve Buscemi), Atlantic City's undisputed czar at a time when Prohibition proved to be a major catalyst in the rise of organized crime in America. Season 4 picks up eight months after the end of Season 3, in February 1924 - the year jazz "really came into being," with fictional dancers/singers as well as the ubiquitous Charleston dance. Having barely survived an overthrow by Gyp Rossetti in Season 3, Nucky Thompson is laying low at the end of the Boardwalk as the season begins. Eventually he'll butt heads with Mayor Bader, battle with his brother Eli about the fate of Eli's college-aged son Willie, and set his sights on the lucrative drug and real-estate opportunities in Florida. Most of the drama in this season's twelve episodes will take place in Atlantic City, and musical showpieces will be set in the Onyx Club (modeled after the Cotton Club), to be run by Chalky White. Action will also take place in Florida and Chicago.
