Paris, 1900: a couple are horribly murdered by a masked man with a metal claw who rips their hearts out. The sole survivor and witness to the massacre is a young girl. Twelve years later in Rome a new wax museum is opened, whose main attractions are lifelike recreations of gruesome murder scenes. A young man bets that he will spend the night in the museum but is found dead the morning after. Soon, people start disappearing from the streets of Rome and the wax museum halls begin filling with new figures...

Standard story of the Phantom does have one major variation - The phantom is not a disfigured individual, but rather is an unwashed orphan abandoned in the sewers under the Paris Opera & raised by rats. The Phantom invokes death upon anyone who dares harm his beloved rats. In fact, The Phantom's nemesis is the chief exterminator who develops a rat-catching machine.
