The Music of Love: Beethoven's Secret Love (2004)

The year is 1817. Minon, a five-year-old girl, leaves her aunt Therese of Brunswick, who has raised her like a mother since her birth, to go and live with her parents, the Count and Countess von Stakelberg. One day, Gabrielle, her housekeeper, who is no longer in her right mind, reveals that her real father is the composer Ludwig van Beethoven. Twenty years later, still intrigued by this confession, Minon decides to unravel the mystery of her origins. She returns to the place of her early childhood, hoping to find the truth with her aunt, who was for years the faithful friend of the great composer.
