Father (Chan Ki-yui) and son (Chan King-sam) join hands to create the two-storied gothic mansion for this suspenseful whodunit whose every corner and/or turnaround seems to be shrouded in great mysteries and overshadowed by ancient curses. Murder takes place in it in the first minutes of the film. The victim is the eldest daughter-in-law of the feudal family who inherited the mansion. Second daughter-in law soon determines to investigate into the murder with the help of a male friend, and uncovers a secret and precarious adultery in the course of it. But the affection that the two develop between each other is also used by other members in the family to attack and make them victims of potential danger. Of interesting note is the character of the housekeeper Aunt Five played by Wong Man-lei for her close resemblance to a similar character played by Judith Anderson in Alfred Hitchcock’s Rebecca (1940) in tone, appearance as well as her omnipresence and wickedness.
