On October 17, 1961, thousands of Algerian-born French citizens took to the streets of Paris, peacefully demonstrating against a curfew imposed on them in response to Algerian nationalist terrorist activities. Participants report that the Parisian police responded with force, beating, shooting and drowning demonstrators, though the official record is silent. Filmmakers Philip Brooks and Alan Hayling investigate this dark incident in French history. Narrator Mark Halliley.
