Between March and October 2000, millions of people around the world took to the streets to denounce poverty and violence against women. The historic World March of Women was a bold initiative of the Québec Federation of Women and represented a turning point in global solidarity. Director Sophie Bissonnette invited five filmmakers from around the world to cover the march. She also asked each one to film an innovative project. Set against the backdrop of a song, 'A Score for Women's Voices' ends at the UN, where women deliver 5 million cards signed during the marches. Their goal? To change the world.
