Ken Burns documents the worst man-made ecological disaster in American history, when a frenzied wheat boom on the southern Plains, followed by a decade-long drought during the 1930s, nearly swept away the breadbasket of the nation. Vivid interviews, dramatic photographs, and seldom-seen movie footage bring to life incredible stories of human suffering and perseverance. Includes bonus features.
