America in 1920. The Great War is over, Wall Street is about to boom and everything is for sale, even the World Series. It is a time of change when women are getting the vote, broadcast radio is introduced, and young people rule the world.
On the beach in southern New Jersey sits Atlantic City, a spectacular resort known as "The World's Playground," a place where rules don't apply. Massive hotels line its famous Boardwalk, along with nightclubs, amusement piers and entertainment to rival Broadway. For a few dollars, a working man can get away and live like a king -- legally or illegally.
The undisputed ruler of Atlantic City is the town's Treasurer, Enoch "Nucky" Thompson, (Steve Buscemi) a political fixer and backroom dealer who is equal parts politician and gangster and equally comfortable in either role. Because of its strategic location on the seaboard, the town is a hub of activity for rum-runners, minutes from Philadelphia, hours from New York City and less than a day's drive from Chicago. And Nucky Thompson takes full advantage.
