Early in the 18th century, Ospedale della Pietà is the biggest orphanage in Venice, but it is also where the most talented of the orphans who live there are introduced to the study of music. Its orchestra is one of the world’s most highly regarded. Cecilia, 20 years old, has spent most of her life in the Pietà and is an extraordinary violinist. Art has opened her mind, but not the doors of the orphanage; this is the only place she can perform, behind a grille, for the rich patrons of the orphanage. That is until a wind of spring suddenly disrupts her life and everything changes with the arrival of the new violin teacher. His name is Antonio Vivaldi.
