香港道士林正(林正英 饰)远赴泰国,施法帮助泰国警方制服了雌雄降头大盗金莎与乃密(周比利 饰),岂料两人的尸体被其师父盗走并炼成强大的阴阳同体尸,且阴阳尸只要获得出生于十灵时的女性便可以成为无敌的至强魔尸。林正返回香港后开始为担任实习医生的女儿林小婷(陈雅伦 饰)的交友问题头疼,施法令觊觎小婷的色狼男医生原形毕露。与此同时,阴阳尸来到香港向林正寻仇,林正师兄被害,不敌阴阳尸的林氏父女选择报警,警探大B(张国强 饰)与林小婷有嫌隙,于是趁机数落父女二人,随林小婷至现场勘查的大B在阴阳尸攻击下一败涂地。林氏一家和大B苦思降服阴阳尸之法,而出生于十灵时的小婷与大B其实就是战胜阴阳尸最强大的武器……The wizard's curse is a monster created by a magician from the brains of two dead criminals and it turns on its creator and kills him. Like the evil villain in the Bride with White Hair it is a bisexual being with the male and female parts appearing alternately. It thrives on killing and eating the brains of its victims and it seeks immortality by eating the brain of the taoist priest's virgin daughter. Copying the Terminator and Terminator 2 movies this creature is invincible and in a scene copied from these movies attacks a police station looking for its female victim.
