Rei Kamiki, a 24-year-old office worker at a Tokyo design firm, visits a clinic for her company health examination. Unfortunately, the clinic is staffed by perverted doctors who secretly subject her to sexual harassment during tests of her vision, heart and lungs, breasts, reproductive health, teeth, body, urine, and blood. Hidden cameras record Rei struggling to stay quiet as the obscene examination makes her knees tremble and drives her to orgasm.
