Ten pin bowling playboy Man-Ying (Jason Pai Piao) travels to the jungles of Borneo in search of his missing uncle (and, more to the point, the valuable jewels that his uncle was carrying). After a run-in with a colony of long-haired lepers, Man-Ying encounters a tribe of snake worshippers ruled over by evil high priest Abdullah, a despicable sex-pest who uses powerful black magic to punish anyone who opposes him.
After witnessing Abdullah's handiwork first-hand (a young woman is transformed into a fanged genital-munching monster!), Man-Ying gets into a fight with the high priest's henchmen which leaves him critically wounded with an arrow in his back. Luckily, he is discovered by a group of busty young jungle women who nurse him back to health, after which he falls in love with their sexy snake priestess Filona (the wonderfully named Pinky De Leon). Once fully recovered, Man-Ying returns to civilisation to settle his uncle's affairs, but before he does so, Filona places a curse on him: any woman that he sleeps with will die a horrible death.
Back in town, Man-Ying cannot control his libido, and has sex with two women (not at the same time; he's not that much of a player), both of whom cark it. Understandably, the police suspect the gigolo of foul play, but, on hearing his crazy story, they are only too happy to accompany him to Borneo where he intends to prove his innocence.
A crazy mish-mash of martial arts, supernatural horror, and sexploitation, Hong Kong/Filipino co-production The Magic Curse compensates somewhat for its low production values, dreadful acting, shoddy direction and terrible special effects with its sheer silliness, a smattering of gratuitous female nudity and some fun kung fu fighting. Hilarious highlights include the aforementioned emasculation by the fanged female, Abdullah levitating skulls, producing magical fireballs, and teleporting himself, and the totally bizarre ending in which a jewelled amulet-given to Man-Ying by a random old man in a cave-miraculously saves the day. Handy that!
