The Lonely Soul in the Black Building

During the Cultural Revolution, the girl Xiao Ju's family was persecuted. Xiao Ju herself was hanged in her own home. The murderer disguised the scene as a suicide... More than ten years later, a movie was being shot intensely, and the sound engineer Huo Feng (Chen Xiguang) (played by Pan Jie) was not satisfied with the effects of the scene, so she took the heroine Yu Hong (played by Pan Jie) back to her residence to do sound effects. The old building where Huo Feng lives is facing demolition, and most of the residents have already moved out, leaving only the old leader Lao Lin, the unemployed young man You Fei, and Huo Feng. Yu Hong saw strange hallucinations in the building, and Huo Feng's recording equipment also picked up strange noises. The two investigated the history of this building and learned about Xiao Ju's injustice. They then realized that Xiao Ju's innocent ghost in the basement demanded his life from the murderer when the building was empty. Lao Lin and You Fei had accidents one after another. Yu Hong discovered that director Zheng Lei (played by Han Xiaolei) was also related to the murder that year, and finally decided to help Xiao Ju get revenge.
