We preview the next film that airs on the PBS documentary series American Experience. "Nazi Town USA" examines the preponderance of fascist groups that sprang up all across the United States during the late 1920s and 1930s - and what was going on that would lead so many Americans to be drawn to fascism. It's a story with some interesting parallels with modern day America. Peter Yost is the writer, director and one of the producers of the film.
