The documentary is the first to describe the big picture of discrimination against foreigners in various contexts, including Koreans in Japan, technical trainees, refugees and Immigration Services Agency detainees. The death of a Sri Lankan woman, who died in an immigration detention center, marks a turning point and public opinion began to demand the abolition of discriminatory policies against foreigners residing in Japan. However, an even stricter immigration law was passed by the Japanese government on March 7, 2023. The film was screened at various festivals in Asia.
