Boardwalk Empire is one of the best shows I've ever seen. The acting and writing are as good as anything you'll see on tv. The production is also fantastic, the attention to detail is just incredible. It tells the story of Atlantic City politician/gangster, Enoch "Nucky" Thompson (Steve Buscemi), and how he runs the town both legally and criminally. He runs it with his brother Elias (Shea Whigham), who is also the Sheriff, and their gang of tough guys. It takes place during prohibition and Nucky is the #1 distributor of illegal alcohol. He does this while doing business with some of the most notorious gangsters in American history like Al Capone, Lucky Luciano, Jim Colosimo, Arnold Rothstein, among others. There's not much I can say that hasn't already been said about this incredible show so just go watch it. You won't be disappointed!
