Raised by his father in the dying town of Paradise Flats, Jack McGreary has learned to live by his wits. The year is 1939. Drought has turned America's heartland into a dust bowl, and the world is on the brink of war. Jack's father wants him to head north to Canada to sign up in the fight against Fascism. But when a pair of fast-talking swindlers named Virgil and Miss Rose blow through town, Jack falls in with them instead. Together, they go on a crime spree across the Southwest, staging a series of inventive and often hilarious cons, while sexual tension between Jack and Miss Rose grows. Someone is being set up.
