In response to the call of the Front de libération nationale (F.L.N., the National Liberation Front), thousands of Algerians from Paris and its surroundings march on October 17, 1961, to protest against the curfew imposed on them. This peaceful demonstration will be violently put down by the police. 50 years on, the filmmaker sheds light on this still taboo subject. Blending testimony and unseen archive footage, history and memory, past and present, the film relates the different stages in these events and reveals the strategy and methods applied at the highest level of the French state: manipulation of public opinion, the systematic challenge of every accusation, the censoring of information in order to prevent investigation.
