Dong-gyu, who lives in Gimcheon, travels to Seoul to show his mother’s Itaewon house. The visitor, Shinji, is Japanese and reportedly involved in human rights activism in Korea. When they meet again to check the house, Dong-gyu learns that Shinji is staying in the country illegally. Even after returning to Gimcheon, Dong-gyu continues to worry about him and suggests meeting in Itaewon on Halloween.
