Bruce Wong (Wong Lung in some versions) searches for his uncle Chen in Manila, Philippines. Instead, he finds Master Tong Oha, who now manages the martial arts school, and learns that his uncle had been killed by the Black Dragon society, managed by Cruz, a man who is feared in the international slave market. Bruce Wong beats up three of Cruz's henchmen who were running after an escaped slave girl. That sets him and Tong Oha as targets for the criminal gang. Cruz has several associates, but it seems that not all of them are to be trusted. After seeing his cousin killed, Bruce Wong forces his entry into the criminal headquarters and one by one kills them all with his bare hands while delivering a blood-curling "cry of death".
