Minami Kojima plays a capable, refined property-management supervisor who despises her incompetent subordinate. When he receives a plumbing complaint, she accompanies him to the resident's disgusting, trash-filled apartment. Her apology is rejected, the older resident begins touching her, and she is raped. Humiliated that a beautiful, classy professional like her is being defiled by a revolting stranger, she feels her life falling apart—and blames it all on her useless subordinate. Worse, he watches the assault. Then she notices him smiling, sporting a triumphant erection at the sight of his hated boss being brought low.
