The portrait of Yvonne Pierron, French survivor of the Second World War, who made her life a real fight against all forms of injustice. After entering into resistance against Nazism, and at the end of this dark period, Yvonne decided to become a missionary Sister, serving the poorest people. This religious commitment leads her to Argentina where she lived for over 60 years, devoting herself to the struggles of the indigenous peoples, victims of their poverty, but also of their origins, which are constantly denied, culturally and socially. Yvonne was coreligionnaire with Alice Domon and Leonie Duquet, the French nuns arrested-disappeared during the Argentinian dictatorship, but Yvonne saved her life by exiling herself in her own country. A wise teacher of multiculturalism. A tireless fighter and marginal militant of the popular up-raising movements of Latin America, in which she was part of the last 60 years. Yvonne, the film, takes us ithrough her life.
