When Mei, a university student, goes to the home drinking party she was invited to, she is told that her female friends have all bailed. The toast is brief, and Mei falls asleep after being drugged with sleeping pills in her drink. This home drinking party was planned to assault Mei. The men toy with her defenseless body and ejaculate inside her. Afterwards, they threaten her with videos they've taken, and after being forced to drink an aphrodisiac, Mei loses her reason and is consumed by her sexual desires.
