Plot synopsis: At the strong insistence of his father, Ushimatsu Segawa conceals his origins from a “buraku” area of low-class “untouchables,” leaving his hometown to serve as an elementary school teacher where he excels and is loved by his students. But he constantly struggles with the secret of his low-birth status and is disturbed by all of the discrimination levelled upon his class. It prevents him from pursuing a romance with Shiho, whom he meets at the temple where he resides, but who descends from a samurai family.
