However, when Amadeus crashes and can no longer perform, the entire financial future of the "Mozart company" is suddenly at risk – along with Maria Anna's personal freedom. In order to save Amadeus' career and herself, Maria Anna is forced to take on her brother's role. Soon, she finds herself caught in a web of royal intrigues, at the center of which is the man who has fallen head over heels in love with her: Antonio Salieri.
