A portrait of America as it went through a profound and exhilarating change in morals and manners from the end of World War 1 to the Great Crash of 1929. With Prohibition the automobile became a portable saloon for young people as a new generation came of age. The striking film footage goes beyond the stereotypes of flappers and gangsters to create a captivating portrait of life on Main Street from the relaxed pace of small town commerce to the frenetic energy of night clubs and jazz bands. As the decade was drawing to a close the drama of Lindberg's flight reinforced the blind optimism of the period.
