The story centers around Vanya, a young girl who, after losing her mother, is adopted by her uncle Aiden and his wife Maira. Aiden, a toymaker, creates a special version of the Sabrina doll for Vanya. Vanya, grieving and seeking to reconnect with her late mother, uses a spirit-summoning ritual involving a Charlie Charlie game. However, she neglects to properly end the session, inadvertently inviting a malevolent spirit into their home. This spirit, known as Baghiah, possesses the Sabrina doll and begins terrorizing the family. As the entity's influence grows, Vanya's behavior becomes increasingly erratic, leading Aiden and Maira to seek the help of paranormal experts to confront the demonic force.
