The compensated-dating ring Sweet Angel expands its reach and intensifies a feud after targeting Black Lion Society boss Moriyama. The gang captures and interrogates woman after woman without identifying the leadership until a tip reveals that Sachiko, daughter of the politically and financially powerful Shiratori family, is a Sweet Angel executive. The Black Lion Society lures her into a trap, captures her, and subjects her to pleasure torture. Sachiko resists out of pride as an executive, but her endurance begins to fail.
