The master of the reclusive martial arts master Chen Shuo, the "Iron Fist Grandmaster" Mo Shan, died suddenly and mysteriously. The official conclusion is that he went crazy while practicing martial arts. Chen Shuo discovered that there were strange pinholes hidden in his master's body, which was suspected to be related to the underground fighting. In order to find out the truth, he sneaked into the "Blood Platform" under a pseudonym and used his fierce punches to attract the attention of gamblers. During the investigation, he discovered that his master's death was connected to the "Council's" plan to plunder secrets. Each clue pointed to different forces: the hypocritical successor grandmaster, the capital tycoon who controlled the gambling market, and the mysterious female intelligence agent with special skills. Chen Shuo pieced together the truth in a life-and-death contest, but he didn't know that he had already stepped into the trap of the master's fall.
