Documentary inspired by the life and work of the Chilean musician and engineer José Vicente Asuar, creator of the first musical computer in Latin America: the COMDASUAR, which was left unused for many years somewhere in the contryside. The reunion of Asuar with this artifact, together with the appreciations of national composers and researchers, converge in the search for a lost story in the sonorous biography of Chile, reconstructing the works that have earned him worldwide recognition for his work in the development of the electroacoustic music.
