In the early 20th century, Countess Carmen Díaz de Mendoza Aguado, inspired yet frustrated by Mozart’s Don Giovanni, sets out to write her own version but struggles with doubt, societal pressures, and a haunting inner voice, leading to her play’s failure. Decades later, fragments of her life and work resurface through obituaries and fading memories. In 2024, a modern composer seeks to rediscover and reinvent her lost opera, conversing with the echoes of the past to reclaim the Countess’s silenced voice and vision.
