The movie is structured much like a murder mystery, albeit one that gives the viewer a fight scene every couple of minutes. There’s a murderer who goes by the moniker Devil Swordsman gallivanting around the countryside in an outfit that looks like a ninja cloak by way of a KKK robe who’s killing all of the major kung fu masters and clan leaders with a single swipe to the face. One of his first victims is the head of the White Dragon tribe, whose son, Shan, is played by Dorian Tan Tao-Liang. Shan naturally assumes the role of detective in order to avenge his father, since that’s what people do in these movies.
Unfortunately the movie The Knife of Devil's Roaring and Soul Missing is not yet available on HBO Max.
