Saki Nakajo, a beautiful and righteous rookie undercover investigator, attends a job interview to infiltrate a notorious human trafficking company. However, during the recruitment exam, under the guise of spying for another company, she is stripped naked and subjected to a thorough physical examination, including her nostrils, ears, and of course, her vagina and anus. Finally, the ruthless president of Sadist sees through her lies… and she is subjected to a series of tortures, including being strangled, punched in the stomach, subjected to stun gun stimulation to the nipples, raped (like a female dog), and subjected to anal waterboarding with a pearl-shaped dildo!
