Raven was once a famed international opera diva with a voice that could melt hearts. But during a performance of La Traviata, she inexplicably killed every audience member present with a single high note. Since then, she has been cursed. Whenever she sings above a certain pitch, her lethal vibrations instantly kill anyone within hearing range. Now Raven lives like a recluse in an isolated Victorian mansion. Driven mad by guilt and despair, she awaits an unsuspecting visitor to sing her murderously beautiful aria to. She lures her prey with promises of fame and fortune. In reality, she wants company in death.
