1962, at the end of the Algerian War, Algerian independence activists are released from Rennes prison. For one night, filmmaker Yann Le Masson films them. They tell him their vision for the future of Algeria and the place women must occupy in the new society to be built. Fifty years later, with the soundtrack missing, Raphaël Pillosio sets out to find these women. Two deaf people set about lip-reading the women filmed by Yann Le Masson, revealing snatches of sentences, words cut short by the camera's shifts. An investigative film in which the few activists still alive discover their old testimonies and tell us their silent story. The reconstruction of the lost soundtrack will remain in suspense; no happy ending will come to absorb the absence, to cancel the ferocious operation of time. An essay film about cinema that depicts their disappearance, and forever keeps them alive.
