Oh-seong is a son of an illegal Mogolian immigrant, and a member of a wrestling team in Nam-cheon high school. He wishes to compete in the National Sports Festival but it is impossible for a stateless person. Oh-seong’s mother, Nyamka, is living with a man named Yeong-cheol who had promised to marry her long ago, but it seems Yeong-cheol won’t keep his words. An unexpected opportunity comes to disheartened Oh-seong, but he gets involved in a serious incident.
