Mami wakes in a pitch-black room wearing a collar and tied to a rope. A creepy man stands before her without saying a word, and before she can understand why or how she was brought there, a life of around-the-clock violation begins. He silently forces himself on her without a moment's rest. When the nonstop sexual abuse finally pushes her beyond her limit, what feelings remain? A carefully built captivity story that goes far beyond an ordinary rape fantasy, showing every step of her fall into complete submission.
