In 1923, the young Kim Shun-Pei moves from Cheju Island, in South Korea, to Osaka, in Japan. Along the years, he becomes a cruel, greedy and violent man and builds a factory of kamaboko, processed seafood products, in his poor Korean-Japanese community exploiting his employees. He makes fortune, abuses and destroys the lives of his wife and family, having many mistresses and children and showing no respect to anybody. Later he closes the factory, lending the money with high interests and becoming a loan shark. The film is told from the perspective of Masao, his legitimate son by his abused and degraded wife, who knows nothing about his father other than to fear him.
