Acting on an informant's tip, narcotics agent Iroha enters the Black Lion Society's hideout alone in a bright red catsuit and walks straight into a trap. Captured and sexually molested, she is forcibly dosed with the same illegal drug she was investigating. Her formidable will holds out against the mounting pleasure until the relentless torture pushes her past her limits. Her trained body awakens to the stimulation, and the disciplined agent ends up craving more.
