The Whirlwind Knight (1969)

Two halves of a treasure map owned by two brothers is the one thing that the Golden Dragon Gang wants to get, and they'll kill anyone who gets in their way. When the gang quickly dispenses with the two brothers in a blitz home invasion, their third brother, returning from ten years of wandering, arrives and teaches the gang a lesson they'll never forget--that is, if they survive at all! Henchman after henchman gets filleted like a brook trout as our hero literally cuts his way through a jungle of sword-wielding thugs, a trio of fancy-weapon gang leaders, and a masked ninja assassin that's killing people on both sides. Who will be left alive to claim the treasure? Find out in this high body-count wuxia classic.
