The Algonquin once lived in harmony with the vast territory they occupied. This balance was upset when the Europeans arrived in the 16th century. Gradually, their Aboriginal traditions were undermined and their natural resources plundered. Today, barely 9,000 Algonquin are left. They live in about 10 communities, often enduring abject poverty and human rights abuses. These Aboriginal people are suffering the threat to their very existence in silence. Richard Desjardins and Robert Monderie have decided to sound the alarm before it's too late.

In barely a century, French peasants have seen their world profoundly turned upside down. While they once made up the vast majority of the country, today they are only a tiny minority and are faced with an immense challenge: to continue to feed France. From the figure of the simple tenant farmer described by Emile Guillaumin at the beginning of the 20th century to the heavy toll paid by peasants during the Great War, from the beginnings of mechanization in the inter-war period to the ambivalent figure of the peasant under the Occupation, From the unbridled race to industrialization in post-war France to the realization that it is now necessary to rethink the agricultural model and invent the agriculture of tomorrow, the film looks back at the long march of French peasants.
