A group of volunteers conduct a psychological experiment in an abandoned hotel. However, when night falls, they find themselves trapped in an inescapable nightmare. As time goes by, strange phenomena and disappearances in the hotel gradually reveal the horrific truth hidden in this place - it was once a mental hospital, and many patients mysteriously disappeared when the hospital was closed. Li Zi, one of the leaders of the experiment, began to suspect that she had an inextricable connection with this hotel. In the process of pursuing the truth, she discovered that the so-called "ghosts" and fears were actually illusions created by the collective psychology of human beings. Although she tried to use psychological methods to solve the mystery and help everyone escape, Li Zi eventually realized that she was just part of this mental experiment.
