From Detroit to Manchester and Boston, countless American towns, streets, and rivers bear French names. But why? Notre rêve américain follows rapper Biz and globe-trotter Jean-Michel Dufaux as they trace the forgotten stories of French Canadians who helped shape American history. Through interviews, archival footage, and on-the-ground exploration, the film uncovers a legacy erased from mainstream narratives — and calls for a renewed connection to this cultural heritage.
