Antique doll. An old curse... Casey, Alexis's little sister, always collected dolls. Her collection included porcelain and rag, antique and new. But the girl became especially attached to one. Alexis decided that this was another quirk of her already strange sister, but she could not even suspect that from that moment the life of their family would change forever... Something supernatural begins to happen in the house where they live: the doors lock by themselves, the stove is boiling on the switched off stove water. Casey also changes: her blue eyes turn green every now and then, she uses outdated words in her speech, and then she has memory lapses. Alexis understands that something has taken possession of her sister. Casey turned from a sweet girl into an evil, uncontrollable creature. After their father and her best friend Casey were seriously injured, the girl decides to stop her sister from doing evil. But for this she needs to deal with one long-standing secret.
