A Thai jungle cop saves a gorgeous girl from the "Worm Tribe." The cop is cursed with seven "Blood Curses" that burst through his leg. He would die when the seventh breaks, but Betsy, the beauty he saved, interrupts the curse with an antidote that lasts one year. Wisely (Chow yun Fat) advises him to return to Thailand to discover a permanent solution. The cop and his allies fight the evil sorcerer of the Worm Tribe, a horrific murderous baby-like creature, and "Old Ancestor," a skeleton with bright blue eyes that morphs into a Rodan-Alien monster.
