There's a mysterious Chinese document that's hidden in the Tower of Death, and evil Japanese occupiers want to get their hands on it. Meanwhile, a Chinese fighter named Mr. An (Bruce Le) is training in the forest, only to be challenged by several Japanese fighters as well as one of the main Japanese henchmen Bolo (Bolo Yeung). He defeats the other fighters, but flees from Bolo when he pulls out a sword. Mr. An and Bolo meet again in a wrestling ring, where Mr. Ang once again defeats Bolo.
