1942, in German-occupied Paris. Younes, a young unemployed Algerian, played by Tahar Rahim (A Prophet), earns his living as a black marketeer. Arrested by the French police, Younes is coerced into spying on the Paris Mosque as the police suspect the Mosque of helping Resistance fighters and Jews by giving them false certificates. Confronted by this barbarism, Younes gradually develops from being a politically ignorant immigrant worker into a fully-fledged freedom fighter. Inspired by a remarkable true story, Free Men is both a heroic tale of tolerance and a harbinger of the colonial conflict that would ensue between France and Algeria.
