The Buenos Aires Children's Trust is a center dedicated to protecting disadvantaged children. In 1939, the world's first symphony orchestra, composed exclusively of blind young people, was founded there. For decades, eleven teenagers devoted themselves to music body and soul. Basilio, the last survivor of that orchestra, is about to retire. The film shows how Braille scores are made and read, how the instruments are played, and describes the story behind each of the Trust's rooms.
