An animated version of Gaston Leroux's everlasting tale of "The Phantom of the Opera". Christine has been acting strange the last few days: she, first of all, got the lead part on a new opera and she's arrogant with people. A masked Phantom lurking in the shadows is haunting her, keeping her away from other men, striking revenge on the world above, but he also has a good side, a side that was tortured since childhood.
