Chan Sau Ying (Ni Tien) is going to die from tuberculosis and even then her husband Chun Yu (Wong Yung) can’t stop abusing her. Her new servant Leung Yi Wah (Chan Sze Ka) takes pity on her and they work together to drown Chun Yu in a pond, but then Sau Ying watches as her husband rises from the swamp and seeks revenge.

Kuei Chih-Hung was making his version of Diabolique here but that movie didn’t end with a naked woman having blood slowly spit all over her and her entire nude body covered by painted spells.

Ghosts that spit green vomit, animal guts falling like rain and a grime and rain filled swamp location make this movie just feel messy and gross, which quite often is how I like it. Sure, it moves slow in parts — it is forty years old, after all — and some of the acting leans toward silly humor when the movie seems deadly serious, but when the last ten minutes give you the sleaziest exorcism you’ve even seen, there are no complaints.
