Plot synopsis: In 1900, the eyes of the whole world are on Paris. The World's Fair welcomed 50 million amazed visitors, and the city celebrated itself in a glamorous era. This period went down in history as the "Belle Époque." Elaborately restored and colorized historical photographs bring to life the exciting life in Paris between the end of the 19th century and the beginning of World War I in 1914. Bicycles, cars, airplanes, moving pictures, newly founded film studios, revolutionary composers and painters, avant-garde ballet performances, fashion houses, summer resorts on the Atlantic coast – life was intoxicating. People celebrate in the variety shows, cabarets, and revue theaters of Paris. Moulin Rouge, Folies Bergères, Bal Tabarin—in Paris, the nights are long and life is too short to sleep through. It is a dance on the volcano, given the political developments in the world.
