Mystery in a Deep House

tells the terrifying story of two policemen in the early Republic of China who uncovered rumors of a haunted house. Detective Qiao Hu and police officer Hua Mu Xiaoqing are full of ambitions and want to solve major cases. However, because the Song family mansion, where the "Song Shenjiu" fortune was made, is haunted, word-of-mouth word-of-mouth from neighbors spreads the panic to everyone, and they are sent to the Song family compound to "catch ghosts." The two people, who were worried about not being recognized for their talents and firmly believed that there were no ghosts, came to the Song residence. They originally thought of finding an excuse to get rid of the problem and quell the haunting rumors. However, after entering the Song family compound, one after another "haunted" incidents continued to occur. The two policemen, who had always been underestimated, truly embarked on a professional investigative journey beyond their own imagination.
