Young wife Itsuki visits a chiropractic clinic after work to treat her stiff shoulders. The gentle, attentive care initially puts her at ease, but the therapist uses smooth talk, special herbal tea, and a supposedly corrective treatment to dismantle her defenses. Her body begins responding unexpectedly to every touch, and the bewildered wife is overwhelmed by sensations she cannot resist. Before she realizes it, she is trapped deep inside the corrupt therapist’s scheme, her reason collapsing in the locked treatment room.
