Als een jonge operazangeres de hoofdrol overneemt in een avant-garde presentatie van Verdi's MacBeth ontketent ze de waanzin van een gestoorde fan. Deze dwingt haar om toe te kijken als hij haar vrienden binnen de opera vermoordt. Heeft de steeds terugkerende nachtmerrie van de zangeres iets te maken met de identiteit van deze psychopaat?
Nee, helaas is Opera nog niet beschikbaar op Netflix in Nederland.
