A French short documentary that delves behind the scenes of the restoration of a 1920s film, starting from a 35mm color print. Set against iconic French cinema locations such as the climate-controlled vaults of the CNC and the Cinémathèque Française, the film traces each step of this meticulous process, from preservation to both mechanical and digital restoration at the Joinville-le-Pont laboratory. This technical and human journey highlights the craftsmanship involved and raises questions about the future of works that are not preserved on film.
