Baseball player Takatsuka is murdered mid-game in front of a large crowd. The autopsy reveals that he has been killed by a needle coated with a poison used by the Ainu tribe for hunting. The next morning, sports photographer Kawase is killed in the same manner. Kawase’s sister, Yuko, hires Taro Banai, the detective with seven faces, to uncover the truth.
