Nicole Védrès' chronicle of Paris from 1900 to 1914 is brought to life through the use of original material, all authentic, secured from more then 700 films belonging to public and private collections. A few of the celebrities of the time shown are Enrico Caruso, Sarah Bernhardt, and Maurice Chevalier.

Romm pulls out all the stops in its selection of documentary material to draw the viewer not only into absolute horror about fascism and nazism in the 1920s–1940s Europe, but also to a firm conviction that nothing of the sort should be allowed to happen again anywhere in the world.
