Haunted orphan Olivia keeps a legion of spirits contained inside a cherished windup melody. When her cruel college roommate Chloe destroys it during a livestream stunt at a deserted hospital, Olivia becomes the vessel for unimaginable fury. Only Amy, the friend who has known her since childhood, can pull her back from the edge. By the end, Olivia escapes behind a mask of innocence as those who crossed her are left dead, broken, or confined to psychiatric wards.
