Orphan Olivia, possessed by countless demons, relies on a music box to seal them. At university, her arrogant roommate Chloe bullies her relentlessly—then smashes the music box at an abandoned asylum for livestream views. Olivia loses control, unleashes the demons, and takes brutally bloody revenge. Her childhood friend Amy snaps her back to reason. Olivia plays the innocent victim and walks away scot-free, while her tormentors end up dead or locked in mental institutions.
