The Big Boss

Cheng Chao-an (Bruce Lee) is a Chinese man who moves to Pak Chong, Thailand, to live with his adopted family and work in an ice factory. He meets his cousins Hsu Chien (James Tien) and Hsu's younger brother by accident when Hsu Chien stands up to local street thugs. Cheng refrains from getting involved, as he swore to his mother to never participate in any fighting. He wears a jade amulet around his neck as a reminder of his pledge. Cheng begins his work at the ice factory. When an ice block is accidentally broken, a bag of white powder falls out. Two of Cheng's cousins pick up the bag and are told to see the manager later that night. The factory is actually a front for a drug smuggling ring led by Hsiao Mi (a.k.a. the Big Boss). When Cheng's cousins refuse to join them, the manager sends his thugs to kill them and dispose of their bodies, thereby keeping the secret safe. Hsu Chien and another cousin go to Hsiao's compound to find out what happened to the two cousins. Hsu doubts Hsiao's claims that he doesn't know anything and threatens to go to the police. Hsiao sets his gang on the duo as a result, and they are killed...
