Am now halfway through The Big Boss. Cheng Chao accidentally pushes a block of ice too hard on a conveyor bridge. The block falls to the ground and breaks into several pieces. Two of the workmen discover that there are packets of opium concealed within the ice, They are called into the manager's office, where they are offered money for their silence and for their allegiance to the opium ring. They refuse, and they are murdered. Two other workers--Hsu Chien and a cousin--investigate their disappearance, only to also wind up dead and missing. When the workmen do not return home, the rest of the workers storm the manager's office, demand to know where their missing mates are, and go on strike. The foreman attacks them. The manager calls their supervisor to send more men to intimidate the strikers. During the ensuing fight, one of them accidentally snatches Cheng Chao's jade token, which smashes into two pieces but frees Cheng Chao from his pledge to not fight again.

Cheng Chao defeats the oppressors. The manager sacks the foreman and promotes Cheng Chao to his position.

I can't say that I enjoy this movie. Bruce Lee is quite passive during the first half, there are too many characters, and the romantic scenes can all be deleted without affecting the story. It seems that Nora Miao makes an appearance as an extra, though, a sidewalk food vendor. Unless I am wrong.
