Opening scene shows cadets at the Imperial Japanese Military Academy in Tokyo, practicing Kendo martial art using bamboo swords (shinai) and wearing protective armor (bōgu). Next the cadets run an obstacle course. We see them leaping over a wall and then running over wooden poles across a deep open pit. They then leap another wall and climb out of a deep ditch and over a stone wall to the top. Next, students are seen demonstrating kendo in a courtyard at the a Military School in Kobe, Japan. Many spectators watch the demonstration.
