At the dawn of the year 1800, not far from Venice, stands the Sant' Ignazio Institute, a cross between an orphanage, a conservatory, and a convent. For years now, it has been home for Teresa, a young woman with a special gift: a visionary talent that allows her to listen to the world around her and transform it, animating it with a new, contemporary, timeless music. An enchantment... that is shattered when reality makes an incursion and brings her back to her duties. Because in the convent everyone calls her “the Mute”, a scullery maid who lives silently and alone. But things are about to change for her. While the convent is in turmoil for the imminent concert that the Chapel Master, the arid and despotic Perlina, is to conduct in honor of Pope Pius VII who is soon to visit, Teresa makes an exceptional discovery.
