Flower and Snake 4: White Uniform Rope Slave
What they share
Both films are directed by Shōgorō Nishimura, and they both carry the raw, sexy mood tags, and they sit in Drama / Horror / Thriller territory. If that's the register that drew you to Flower and Snake 3: Punishment, the second film will land in a comparable space — through a different lens.

What Flower and Snake 4: White Uniform Rope Slave is
Operating room. Hum of the drill. A dentist and his nurse find ways to monetize their patients' vulnerability. He develops a fixation on two new clients, unaware of the women's own games. Nishimura's erotic thrillers are not for all tastes.
