Six women, approached by female staff under the pretext of a "media awareness survey" and gathered casually as if for a part-time job, were lured into a screening room. To their surprise, the screening turned out to be a pornographic video. Even more shocking was the presence of an unknown man seated beside them. As sexy scenes played on the TV monitor, the man and the women gradually became aware of their sexual roles, transforming into primal male and female instincts.
