Agent Yamamoto grows angrier by the day as one colleague after another disappears during a serial narcotics investigation. She discovers that the vicious Black Lion Society may be behind the case, but walks into its trap and is captured. Restrained and unable to move, she is humiliated, violated, and dosed with the very illegal drug her team was pursuing before being plunged into a nightmare of pleasure. Her trained body fights desperately against wave after wave of stimulation, yet it responds against her will and she is forced to climax repeatedly in a state of panic. Driven beyond her limit, Yamamoto becomes crazed with pleasure; her powerful body arches as her lust fully awakens in an overwhelming orgasmic hell.
