This documentary follows a female prison guard at a rehabilitation facility called "Sex Crime Eradication Treatment Center" as she conducts sexual therapy on a severely ill inmate confined to solitary confinement. Her mission is to treat his overwhelming libido, which led him to commit past crimes, through sexual acts. As a professional, she never reveals her emotions during her shift, her dedication is truly admirable. She engages in cold, detached sex with the inmate, who struggles to control his impulsive desires. Despite his sudden thrusts, creampies, and handjobs, she maintains a stoic expression throughout.
