When an aspiring composer (William Finley) has his music stolen by acclaimed producer Swan (Paul Williams), he sets out to take his revenge. But in the course of seeking justice, the composer is badly injured and disfigured. Now totally insane as well, he dons a mask and a cape and becomes the Phantom. And the Phantom's thirst for vengeance will end with him or Swan dead.

A more than a little camp musical parodying Phantom of the Opera as much as Faust, also starring Jessica Harper (SUSPIRIA).
