Christine Daaé, a talented young singer, after being discovered by the known playboy Comte Philippe de Chagny, is sent to the Paris Opera House by her new patron to be classically trained. Unfortunately, her point of contact, the manager, Gérard Carrière, has just been fired. The new managers -- Cholet and his wife, Carlotta -- put Christine to work in the costuming department instead. After a short time there, Christine is overheard singing in the dead of night by the fabled Phantom of the Opera that lurks far below the theatre. The Phantom soon introduces himself as Maestro and decides to take Christine under his wing, training her voice himself. However, all of their plans upend when Comte de Chagny returns to Paris.
