Murder in the Orient

During World War II, When the Japanese were fighting in the Philippines, they buried a stash of gold. They decided to abandon the traditional "treasure map", deciding instead to engrave directions to the loot on two separate samurai swords. Now, in the swingin' seventies, the nefarious Golden Cobra Gang has one of the swords. They desperately want the other one. Gustavo, a higher-up in the organization, really wants to please the head boss, King Cobra, so he pulls out all the stops to get the missing sword: he brings in Kang the Butcher, a ruthless assassin, and of course Turko. But he makes a fatal error in his quest. He kills the sister of Lao Tsu (Leo Fong). Now Tsu, a peaceful Hong Kong martial arts instructor, must travel to Manila to get revenge. On top of that, the American Paul Martelli (Ron Marchini) is caught up in the madness because he was involved with Tsu's sister.
