Beatriz Ferreyra is a concrete music artist based in France, but of Argentinean origin, who has developed her own language in experimental music. This documentary has as a script the scores elaborated by Ferreyra along the years, the sounds and silences she built, and the radical proposal that the image is at the service of the sounds.
