Finished watching The Big Boss. The workers celebrate Chen Chao's promotion in their neighborhood. So does the manager, who takes him away to a restaurant and gets him so drunk that he ends up in the room of one of the prostitutes at the party. The prostitute later reveals that she used to work as a maid for the big boss who owns the ice plant, and hints that the big boss couldn't have made money producing ice alone.

Chen Chao sneaks into the ice plant at night and discovers an opium laboratory, and that there are opium packets inside blocks of ice. He discovers more, though--the four murdered and missing men are trapped inside ice blocks as well. The big boss's son and their minions follow Chen Chao to the ice plant. A big fight ensues, but Chen Chao takes all of them down, including the big boss's son.

Back at home, Chen Chao discovers that everyone in the household has been massacred. Chen Chao swears vengeance and proceeds to the big boss's huge residence, where he renders vengeance. There is much bloodshed. That final fight between Chen Chao and the big boss is fantastic.

If Fist of Fury ended with B.L. being gunned down by a police squad, this one ended with him being arrested.
