Young female teacher Kyoko Miyake relocates to a small seaside town with her runaway little sister, but their new life is complicated by hoodlum-like Jiro Yamazaki (the black sheep of the title) who is related to the family hosting them and whom they keep running into, but can't help but to feel sympathy for. Of course, rumours start fast in a small town, but delightfully she doesn't really care at all. This is another very solid Shogoro Nishimura film.
