When Sophie, at the age of six, unfortunately became an orphan, custody was assigned to her estranged aunt Annabel. The two moved into a large Victorian house, where Sophie found a locked wooden box with a strange symbol painted on it. She was eager to contact her niece Annabel, so she broke the lock and revealed a beautiful music box. Every time the music box is wrapped and played back, it is surprising that the creepy melody plays for a longer time, which is more attractive to Sophie. When the music box began to affect Sophie's behavior and health, Annabel sought the help of a child psychologist and a doctor with a thousand eyes. He soon found that the music box was possessed by an evil spirit, which tried to harass Sophie and destroy Annabel. As the lingering atmosphere intensified and time began to run out, Annabel found herself racing against the melody of the music box before the last note sounded to beat the spirit.
