After a string of bad luck, a debt collector has no other choice than to spend the night in a haunted temple, where he encounters a ravishing female ghost and later battles to save her soul from the control of a wicked tree demon.
Ning Tsai-Shen, a humble tax collector, arrives in a small town to carry out his work. No one is willing to give him shelter for the night, so he ends up in the haunted Lan Ro temple. There, he meets Taoist Swordsman Yen Che-Hsia, and the beautiful Nieh Hsiao-Tsing, with whom he falls in love.
