At the dawn of the 20th century, America west of the Mississippi was wild and untamed, featuring formidable landscapes and treacherous rivers. But in the following decades, industry and opportunity transformed the region into an economic and political powerhouse that drove change across the country and the world. Presented for the first time in color, revisit lands made famous by Buffalo Bill, championed by Teddy Roosevelt, and developed by opportunists seeking adventure and fortune.

It's the 1920s. America is on the rise, and so is a dark underworld run by a new kind of criminal, one that is organized, sophisticated, and ruthless. For the next 40 years, legendary gangsters like Al Capone, Lucky Luciano, and Frank Costello build vast empires thanks to bootlegging, illegal gambling, and shady alliances with politicians. From the Black Sox Scandal to the St. Valentine's Day Massacre, follow the violent rise and fall of organized crime, presented in color for the first time through remastered archival footage and never-before-broadcast home movies.
