In 1777, 21-year-old Mozart leaves a secure life and job in Salzburg to become a composer. He must overcome his mother's tragic death and his oppressive father to break through.

Mozart, aged 25, faces an uncertain future in a city where he has few friends. He finds solace and security with the Weber family, particularly with Constanze, with whom he falls in love.

Following his father's death, Mozart's music takes on a new level of intensity and emotional depth as he grapples with the numerous losses he has experienced in his short life.
