It tells the thrilling story of two policemen in the early Republic of China who uncovered the haunted house. Inspector Qiao Hu and policewoman Mu Xiaoqing were full of ambition and wanted to solve the big case, but because the Song family mansion, which made its fortune from "Song Shen Liquor", was haunted, the neighbors spread the news, and everyone knew about it and panicked. They were sent to the Song family compound to "catch ghosts". The two people, who thought they were not appreciated and were worried, but firmly believed that there were no ghosts, came to the Song family mansion, hoping to find an excuse to perfunctorily deal with the matter and quell the haunted rumor. However, after entering the Song family compound, one "haunted" incident after another continued to occur. The two policemen, who had always been underestimated, truly embarked on a professional investigation journey beyond their imagination.
