A realistic portrayal of a beautiful girl's after-school suffering. She faces daily punishment and forced physical servitude, made to hold a bucket for hours while desperate to urinate, only to be denied relief. Told her repentance is insufficient, she's brought to involuntary urination with electric stimulator torture, then coerced into begging for further punishment, receiving spankings so severe her buttocks swell. Harsh penalty games repeat relentlessly, each time capturing the girl's emotional turmoil and distress.
