In eighteenth-century Venice, Italy, the finest musical performances are heard at an orphanage called the Ospedale della Pieta. Hidden from the audience is an orchestra of young orphan girls, some with physical disabilities and illnesses. Padre Antonio Vivaldi, their music teacher, is inspired by the talented and determined young girls. When Vivaldi and his students are separated, Vivaldi is inspired to compose a set of concertos that mark the passing of time--the great baroque masterpiece entitled The Four Seasons.
