Silver Maid, a young girl, becomes caught up in the struggle between two warring sects, the Red Devils and the Black Devils. At the same time, she is on a quest to find the Fairy Fungus, which is the only means of curing her ailing grandfather. Getting it requires that she defeat a quintet of vermin-based fighters known as the Five Poisonous Creatures, who include among their number a giant puppet snake. This accomplished, everyone sets off in search of a magical superweapon called the Sacred Tooth.
