On September 13, 2018, President Emmanuel Macron visited Josette Audin at her home in Bagnolet to ask for her forgiveness, presenting her with a declaration acknowledging that her husband had died under torture at the hands of a "legally established system" implemented by the former French colonial power in Algeria. This acknowledgment, however belated, is a victory for Josette Audin and her family, but above all, it is a victory for human rights, achieved together by mathematicians and historians. This film retraces this shared commitment against torture and state abuses, first within the Audin Committee and then within the Committee of Mathematicians, which also intervened to support other mathematicians imprisoned and sometimes tortured around the world.
