Acclaimed director Chu Yuan was credited for bringing mystery and detective thriller ingredients into his atmospheric and character-rich martial arts epics, and this is one of the most impressive examples. The title refers to the nickname of a notorious rapist-murderer who swoops down to destroy one swordsman's fiance and frame another. Or does he? The two tragic men team with a beautiful swordswoman searching for her missing father to find the truth — only to discover incredible traps, ambushes, duplicity, avarice, and betrayal between them and the mystery's solution. They survive blades, bombs, and even poison gas to reveal priceless treasure and coveted kung-fu manuals before the Bat is beaten at his own insidious game.
