Through a conversation with João Bénard da Costa and his ideas about the Portuguese cinema, an interaction between the construction of the documentary and the sights and sounds clips from some movies is established. Despite the difficulties, the films continue to exist and to resist. Is it worth it? What would happen if they disappeared? Each viewer must find their answer. This film aims to be an approach to Portuguese cinema in its hundred years of existence, opening, hopefully, ways for their dissemination and making light for its knowledge.
