A warrior, Wei Jian Tsen, acquires a mask that can be split in halves representing good and evil. When the two halves are combined, the wearer gains untold power. Wei Jian Tsen's second wife, Mei Tu, becomes influenced by the Black Flower Cult, a murderous group that uses sorcery. In response, Wei has her executed, causing their only son, Fang Tu, to leave their clan. Wei divides the mask and entrusts half to a Shaolin monk, Master Kai, while keeping the other half himself. Fang Tu kills his father and takes his half. Kai requests that the player transport the other half to a secret sanctuary. The player is assisted by an ally, Wu Ching.
