Jin Yu was an ordinary office worker, but suddenly he began to encounter a series of bizarre incidents. He frequently saw strange figures invisible to ordinary people, and heard strange voices whispering in his ears. One day, he worked overtime at the company until late at night. When he was taking the elevator alone, the elevator suddenly shook violently and then stopped on a non-existent floor. The door slowly opened, and a woman with disheveled hair appeared in front of him. After that, similar strange things continued to happen. Li Yang told people around him about his experience, but no one believed him. Everyone thought he had a mental problem, and he was forcibly sent to a mental hospital by his family.
