Frank has a gift for finding his customers the music they need to hear. When he meets Ilsa Brauchmann, a mysterious and beautiful woman with no ear for music, and engaged to another man, he falls in love. She is way above him, she will never be his, but he will take her on a journey through music.
Twelve years later Ilsa returns to find Frank. The shop has gone; no one knows where he is; perhaps he’s dead. All that remains is a series of clues, each one related to music. Ilsa resolves to follow them and bring Frank back to life with music, just as he once did for her.
