The film tells the story of a largely female rock band who acquires an unpublished score by composer Niccolò Paganini and decides to record it.

When the band films a music video for the song in Paganini's ancient home, it awakens the spirit of the deceased composer and unlocks a portal to Hell.

At La Casa di Sol, an ancient Venezian home of various composers through the ages, a young violinist practices a piece by Paganini and then inexplicably electrocutes her bathing mother with a hairdryer.

Meanwhile, Pickett travels to St Mark's Campanile, where he throws the money Daniel gave him off the roof and invokes Paganini's curse.

Rita, the bass player, is confronted by Paganini, whom she assumes is Daniel wearing his costume from the video shoot; however, he stabs her to death with a violin.

After quickly exiting the house to greet him, she finds he has vanished and discovers a bewildered Kate in the empty courtyard pool.

Paganini emerges, stabbing Sylvia with his violin and sealing the unconscious Kate in an empty double bass case.

Pickett emerges from the car as Sylvia explains that she was the one who, as a child, murdered her mother in the house, and that she was condemned to relive the experience they just went through eternally.

As a new family arrives, Kate thinks she is free to go, but Pickett explains that he hates people who sell their souls for fame and success and stabs her to death.
