The Golden Goddess Kalong (1966)

In order to save her boyfriend Yod's life, a young woman named Khun becomes the mistress of a sadistic lord (whose wife isn't much better). Once Yod finds out about it, he breaks up with her and she kills herself. Her ghost returns for revenge. This same exact story (set in 1905) was filmed again in 1981 as แก้วกาหลง ("Glass Kalong").
