To Kill a Mastermind 1979

Synopsis

The Chi Sha Clan is a vast network of deadly criminals proficient in martial arts. Growing in number at an alarming rate, the Imperial Court orders Yang Chen-yu and his followers to eliminate them. However, doing this proves difficult as no one knows the identity of the mastermind behind the Chi Sha, not even its own members. Spies infiltrate the organization in an effort to destroy from within. But then, no one knows who the spies are and after a few ambushes and security breaches, clan deputies begin suspecting one another of being traitors. With the Chi Sha dwindling in numbers, it's only a matter of time before the mastermind must reveal himself.
