Biography of Julian Gayarre (1844-1890), one of the best tenors of all times. At 19, a professor at the Conservatory of Music in Madrid heard him singing for the first time and offered him a scholarship to continue his studies. His artistic life runs between continued success, becoming the world's greatest tenor. But in 1890, while singing at the Teatro Real in Madrid, a failure in his voice is like a cruel reminder of what would happen a few days later: his death at a young age. The doctors gave a diagnosis, but his friends know that Julian Gayarre died because he could not sing anymore.

Gustavo is morbidly dominated by his mother, Doña Leticia, who refuses to accept another woman in her son's life.
