Marie sits at her piano through many long hours, composing. Suddenly, a different music rings out in the room--a piece John, her first love, had been working on before he died in a plane crash. John's music is more powerful than Marie's, and it shatters her fragile universe. Paralysed by her sense of guilt, Marie struggles with John's phantom: could she have been responsible for his death? Memories, emotions, and hallucinations are the invisible and mysterious forces that threaten to destroy her. To overcome them, she will have to fight.
