In the shadows of the Paris Opera, a phantom roams. Skillfully, it hides from the eyes of people, yet it influences the happenings on stage, as it helps the singer Christine Daaé become the star of the ensemble. When the grotesquely ugly phantom reveals itself to her, it first brings a great shock, soon followed by love, triggering a comically turbulent avalanche of events. Based on Leroux's novel, Andrew Lloyd Webber's 'The Phantom of the Opera' is the most successful musical in the world.
