Sonny Chiba as Doshin So,Originator of Shorinji Kempo. This was Chiba's first of two portrayals of a real life martial arts masters ( His portrayal of his Sensei Mas Oyama in "The Champion of Death" being his second). Incredible fight scene choreography featuring authentic shorinji kenpo techniques, though of course it wouldn't be a Sonny Chiba film without his removal of body parts of several opponents. The plot involves life in postwar Japan in which Doshin So comes to the aid of numerous war orphans as well as a young girl who is forced to become a prostitute to survive.
