Hong Kil Dong plot
Hong Kil Dong is the bastard son of a high-ranking government official who, along with his mother, tries to escape the humiliation of his stepmother. During their journey, they are ambushed by bandits. A good-natured old man named Mu On will save them with his martial arts and teach Hong Kil Dong the same techniques. One day Hong Kil Dong meets a young woman whom he falls in love with. However, he cannot marry her because she comes from a higher class. Dissatisfied with the feudal system, Hong Kil Dong leaves his hometown to protect the local population from corrupt government. He will also repel the Japanese invasion of ninjas. Then he leaves with his girlfriend and mother to another country without class distinctions.
