Korean martial arts action. In the 1930s, young Choi Baedal (Yang Dong-geun) travels from his native Korea to Japan, in the hope that he can join the Japanese airforce and train to become a pilot. Experiencing prejudice in Japan because of his Korean background, Choi is shocked to find that he is not allowed to compete in any of the local martial arts tournaments. His determination sees him retreat into the mountains, where for two years he trains until he feels he is ready. Taking on the best fighters in the country, Choi soon establishes himself as the greatest martial artist in Japan, so successful that he can set up his own training school.
