"Please don't help me..." Pleads a young girl, captured by merciless men for an outdoor gang rape, her mind slowly eroding under senseless humiliation and abnormal confinement. Used as collateral for her parents' debt, she is sealed alive inside a metal drum, forced into inhuman treatment as daily interest payments. Within the drum that has become her dwelling, under 24-hour constant surveillance, she is made to endure endless acts of degradation. Her overly sensitive big tits are tormented, intense sexual acts filled with overwhelming pleasure are inflicted upon her, and her lewd appearance is vividly captured. What will become of her in the end...?
