1934. The Dustbowl. The last great age of magic. In a time of titanic sandstorms, vile plagues, drought and pistilence - signs of God's fury and harbingers of the Apocalypse - the final conflict between good and evil is about to begin. The battle will take place in the Heartland of an empire called America. And when it is over, man will forever trade away wonder for reason. A sweeping epic that is both challenging and highly accessible, this one-hour HBO drama series focuses on the primordial conflict of good vs. evil, as played out against a pair of vivid and unusual backdrops: a traveling carnival working the American Dustbowl circuit, and an evangelical ministry in California.
