A mysterious man, who's face we never see clearly, relates in a chilling monologue his experiences having sex with older women for money to finance his heroin addiction. He presents the scenario in a very matter-of-fact, detailed, straightforward manner, refusing to assign blame or draw conclusions. How does he regard his predicament? Is he proud of his ability to survive? Or simply too numb to have any perspective on how his actions appear to others?
