There is a chiropractic clinic still operating in Tokyo's Gotanda district. A lewd chiropractor secretly films young women who visit the clinic, capturing their actions on video. Some girls end up sucking his cock during treatment, while others continue visiting despite receiving overly aggressive therapy. This chiropractor possesses an extraordinary technique that easily captivates girls. Though he pretends to be kind-hearted, he is actually a devil in disguise. Tonight, as always, the clinic sign quietly glows in the darkness.
