A young American woman, Suzy, arrives in Germany to study dance at a prestigious ballet academy in Munich. On the night of her arrival, she is mysteriously denied entry to the school, but she sees a girl fleeing the building — the same girl who is brutally murdered later that night. The next morning, the misunderstanding is resolved, Suzy is admitted, and she begins her classes. She is placed in the school’s boarding house, where each night she is given wine laced with a sedative. Despite this, Suzy senses an ominous presence in the school and becomes determined to uncover what danger lurks within.
