Lin Xiaoxia, a 28-year-old freelance writer, was interrupted by a mysterious phone call at midnight. A woman's cry for help came from the other end of the phone, but the number she called back was empty.
Lin Xiaoxia and her best friend Su Xiaoyu conducted an in-depth investigation, and the clues led to an old house in the old city. The dilapidated Qingtian doll in the house and the strange noises coming from the basement are indescribably weird. What's even more shocking is that Lin Xiaoxia saw the exact same person in the mirror as herself in the basement mirror. She actually claimed that she was sealed in the mirror world by Lin Xiaoxia 20 years ago.
During the investigation, Lin Xiaoxia discovered that her memory loss was related to the incident 20 years ago. The owner of the antique shop, the psychiatrist, Police Officer Chen, and Granny Zhang were all involved in this mysterious incident.
The ancient spell in the diary brings Lin Xiaoxia into a mirror world that is dark, broken, and full of danger. In reality, Su Xiaoyu disappeared mysteriously. As the investigation progresses, Lin Xiaoxia discovers that the old house was once a cult stronghold, and she was once a member of the cult. The owner of the antique shop was actually the leader of the cult, and he was planning to use the man in the mirror to achieve immortality.
Can Lin Xiaoxia escape from the mirror world and rescue Amelia Su? Can an ancient spell seal the man in the mirror? What is the outcome of this 20-year nightmare?
