Cheung Pooi-Saan

They brutally killed his wife, wiped out dozens of his innocent people, and burnt his entire village down to a charbroiled crisp. Now, master Liou Wen-lung is out for revenge. Armed with a near-invincible sword style and a pack of killer darts, he heads out to settle a 10-year old grudge with the cold-blooded evildoers. Joining him is his son, an orphan named Yu Sien and his trusty servant.

Ling (Lo Lieh) and Guan are the Black and White Chiefs of the Eagle Escort security firm: during the opening credit sequence, we see them recover a stolen shipment of gold; by the time the credits have run, the two are literally knee-deep in bodies.

Jiao is framed for rape and murder (and, later, two more murders) by Chen and his son - the same people who framed Jiao's father and left him orphaned. Into the mix comes THE LADY OF THE LAW, Miss Leng, whose job it is to find the guilty. This she does, and she and Jiao find themselves battling pretty much everyone else who's appeared in the movie up to this point.
