Yuna has had a smooth life and is well known for her beauty at university. When she is invited out drinking by a fellow student, she is told that her female friend who was supposed to come has cancelled at the last minute. The toast is short-lived, but Yuna falls asleep after some sleeping pills are added to her drink. The men rape her as much as they want while she is asleep, and cum inside her. Afterwards, they give her an aphrodisiac, and when she wakes up, she loses her reason and is consumed by sexual desire.
