Summer 1940. As France falls under German occupation, its industries are transformed into engines of fascist profit. Once hailed as a national hero and pioneer of the modern automobile, Louis Renault turns his vast factories to producing vehicles for the German army. To some, he is a pragmatist protecting his workers; to others, a symbol of greed and collaboration. This film uncovers how one of France’s richest men — decorated for his service in World War I — became one of the most hated figures of World War II.
