Agent Mio investigates a string of missing narcotics officers and traces the case to the vicious Black Lion Society, only to be caught in its trap. Restrained and unable to move, she is violated, injected with the very illegal drugs she was pursuing, and subjected to relentless humiliation and pleasure torture. Her trained mind and body resist, but wave after wave of forced orgasms leaves her panicked, rolling her eyes and climaxing repeatedly. Finally pushed beyond her limits, the once-disciplined agent loses control and becomes consumed by unstoppable sexual pleasure.
