Yuna is sold to pay off her father's debt, and a filmed sex video is spread through underground channels. Men who see that video appear one after another as customers. Starting with a man who gives a gentle impression, a man who restrains her hands and feet with handcuffs, a man who makes her bite a ball gag and catches her drool with his own body - Yuna is toyed with by men with various fetishes. Eventually, she is surrounded by five men and subjected to the utmost rape.
