A women's clinic hides a sinister secret. An aphrodisiac heats patients' bodies while a group of doctors examines and touches them, making their sensitivity soar.

Stripped to expose their genitals and anus, they are restrained on the examination table and plunged into a hell of pleasure, screaming through unfamiliar sensations before climaxing with obscene cries.
