Plot edit

The film presents a fictionalized account of the early life of Nannerl, sister of Wolfgang Amadeus Mozart. A cracked carriage axle forces Leopold Mozart and his family to spend a few nights in the nearby Abbey of Fontevraud where Nannerl develops friendship with Princess Louise Marie of France who is being brought up there. This leads to an encounter with Louis, Dauphin of France. Nannerl wants to compose music but her father, Leopold, forbids it. The recently widowed Dauphin takes an interest in her and her music that edges toward romance. But he breaks off the relationship when he becomes engaged to Maria Josepha of Saxony. Princess Louise enters a convent and urges Nannerl to stay away from her brother the Dauphin. Both women reflect on how their fates would have differed had they been born male.
