Saki Ninomiya takes on an even more extreme production than ever before. Two people living happily are suddenly seized by a terrifying force, dragged into an abandoned building, and completely dominated. The film unleashes extreme scenarios including deep throat, spanking, and having her tongue clamped with clothespins. Saki is forced to endure filth and humiliation, her mind and body gradually breaking down. This marks the first step in her total collapse.
