After daughter-in-law Xiao Fang married into Xiao Liang's family, she discovered that a bizarre secret spanning over twenty years was hidden in the house. Father-in-law Old Ding kept a utility room locked exclusively, strictly forbidding anyone from approaching. Every late night, a desolate woman's weeping and opera singing would always drift out from inside. Blood-stained traces frequently appearing in the courtyard, ghost shadows in the middle of the night, and brutally killed poultry happened one after another, making Xiao Fang and her husband Xiao Liang panic. The couple suspected that their father-in-law was hiding an outsider privately, and several attempts to probe and question were strongly blocked by the father-in-law.
