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.

Scenes and images from the French Communist Party's (PCF) 1937 Congress in Arles. La Grande Espérance highlights some of the PCF's new concerns under the Popular Front: a warning against international fascism, a desire for organic unity, and the defense of national heritage and regional cultures. It also reveals the first signs of a cult of personality surrounding Maurice Thorez. La Grande Espérance was screened (and possibly re-edited) after the Liberation. A commentary was then added to the credits emphasizing the continuity of the Communist Party’s political line and the sacrifice of its activists during the war. Today, only this post-1945 version exists.
