 Sanshiro, a strong stubborn youth, comes to the city to apprentice at a jujitsu school. His first night, he sees Yano in action, a master of judo, a more spiritual art, and he begs to be Yano s student. As the youth learns technique, he must also learn "satori," the calm acceptance of Nature s law. If he can balance strength and control, then judo may become the training regimen for the city s police, Sanshiro can gain respect from an old teacher in a jujitsu school, and he can win the hand of Sayo, that teacher s daughter, who is also sought by jujitsu s finest master, the implacable Higaki, who vows to kill Sanshiro in a midnight fight on a windswept mountainside.
