At the seashore, in the quiet mountain valleys, and amidst the urban chaos, this documentary captures masochistic women exposing their most intimate areas in humiliation, obeying the trainer's commands. In PART4, the film portrays Nene, a married woman possessing a virtuous soul and a prostitute's body, and Yuna, a young girl whose vaginal sensitivity is still undeveloped. Their distinct charms and conflicted emotions while submitting to the trainer's orders weave together a fantastical visual experience.
