The film explores the history and persistence of discrimination against the Burakumin, a group of outcasts in Japan historically referred to by names such as eta and hinin. Despite the 1871 "Emancipation Edict" abolishing their outcast status, prejudice remains, with areas they lived in continuing to be referred to as "Buraku." The film delves into the origins and evolution of this discrimination, using events like the "Tottori Loop Trial" to highlight the deep-seated and ongoing nature of these biases in Japanese society. It examines why this discrimination endures and the complexities of addressing it.
