Plot:

Young swordsman Lung Fei (Derek Yee) encounters strange omens portending the death of his fiancee Ting Tzu-chu (Pan Ping-chang). His enquiries with the help of Chief Constable Tieh Hu (Sun Chien) reveal an astounding story.

Two sisters are married to two classmates. Ting Peng (Wang Jung) and Hsiao Hsuan (Yueh Hua). Both wives give birth on the same day. Ting's wife has a son, and knowing Hsiao's contempt for girls, has her own son exchanged for her sister's baby girl. Hsiao's wife holds up the baby boy, exposing a birthmark identical to that of his real father Ting. Hsiao sees the similarity, and immediately suspects her of adultery with his classmate. He kills mother and child in a jealous rage and then arranges a series of devious frame-ups. Ting's wife has died in the meantime, and the whole twisted truth does not come to light until Hsiao attempts to bury Tzu-chu alive, not realising that she is in fact his own daughter. Lung intervenes, and Hsiao goes berserk and kills himself.
