Driven by a strong sense of justice, beautiful rookie undercover agent Saki Nakajo infiltrates a corrupt black company involved in human trafficking by attending a job interview. However, as part of the hiring test—ostensibly to detect rival spies—she is stripped completely naked and subjected to a full-body inspection. Every orifice, including her nostrils, ears, anus, and vagina, is meticulously examined. When the cold, sadistic company president sees through her lies, she is subjected to brutal torture: choking, repeated belly punches, nipple play, electrostimulation with a vibrator, deep throat forced fellatio, forced bestiality as a female dog, and anal insertion of a pearl dildo. This grueling ordeal becomes a series of trials that test her sense of justice and inner resolve.
