that Garron and Christine are responsible for drugging her, orders Raoul to arrest them, but he says he cannot because there is no evidence. Biancarolli says she will forget the affair only if Christine's performance is not mentioned in the papers. The following night, the Phantom kills Biancarolli and her maid, and the opera is subsequently closed. After some time, the opera's owners receive a note demanding that Christine replace Biancarolli. To catch the Phantom, Raoul comes up with a plan: not let Christine sing during a performance of the (fictional) Russian opera Le prince masqué du Caucase ("The Masked Prince of the Caucasus") to lure the Phantom out into the open. Garron plans to have Liszt play Claudin’s concerto after the performance, but the Phantom strangles one of Raoul's men and heads to the auditorium's domed ceiling. He then brings down the large chandelier on the audience, causing chaos. As the audience and the crew flee, The Phantom takes Christine down underground. He tells Christine that he loves her and she will now sing all she wants, but only for him. Raoul, Anatole, and the police begin pursuing them underground. Just as the Phantom and Christine arrive in his lair, they hear Liszt and the orchestra playing Claudin's concerto. The Phantom plays along with it on his piano. Christine watches, realizing the concerto was written around the melody of a lullaby she has known since childhood. Raoul and Anatole hear the Phantom playing and follow the sound. Overjoyed, the Phantom urges Christine to sing, which she does. While the Phantom is distracted by the music, Christine sneaks up and pulls off his mask, revealing his disfigured face. At that same moment, Raoul and Anatole break-in. Claudin grabs a sword to fight them with. Raoul fires his gun at Claudin, but Anatole knocks Raoul's arm, and the shot hits the ceiling, causing a cave-in. Anatole and Raoul escape with Christine, while Claudin is seemingly crushed to death by the falling rocks. Later, Anatole and Raoul demand that Christine choose one of them. She surprises them by choosing to marry neither one of them, instead choosing to pursue her singing career, inspired by Claudin’s devotion to her future. The film ends with Anatole and Raoul going to dinner together.
