When 17-year-old Emma moves into her stepfather's Victorian mansion, she senses something is deeply wrong. Locked in the attic is an antique porcelain doll—pale face, hollow eyes, a smile that never fades.
Her stepsister Brittany doesn't care. For TikTok clout, she films the doll and sparks a viral challenge. Three days later, Brittany's joints bend at impossible angles. Her skin cracks and peels away, revealing cold porcelain beneath. And the doll in the attic? It's starting to look human.
Emma's father, a supernatural investigator, warns her: the doll carries the soul of a girl sacrificed a century ago—and it's swapping bodies with Brittany. But no one believes Emma. Brittany weaponizes her new "perfect flexibility" to join the cheer squad, steal the quarterback, and climb the social ladder.
Then the quarterback vanishes. Brittany becomes a monster feeding on human blood.
And that's when Emma learns the truth: Brittany was never the target. She was the bait.
The entity wants someone else. Someone who always smiles. Someone who pretends everything is fine.
Emma's mother.
