Junxiang wakes up from a coma and realizes she is surrounded by darkness, her hands shackled, seemingly in a boiler room of a building. Suddenly, a person in strange clothing approaches her, their voice sounding odd, clearly emitted through a voice changer. Junxiang's father, Daisuke, is the president of a construction company. After her mother’s death, he often had affairs with his secretary and his relationship with his daughter is not good. He hasn’t noticed that his daughter has been kidnapped. When the phone rings and he hears Junxiang's trembling voice, Daisuke begins to realize the seriousness of the situation. In this nowhere-to-hide chamber, Junxiang is violated. However, amid the entanglement, she develops subtle feelings for her captor... Starring an AV actress, this is still an old cliché story about captivity. By saying this, you can understand the kind of power this film relies on, right? Yes, more direct sexual scenes, more aggressive sounds, a more thorough dark love, and something even more distressing! Of course, this is not a film, so if you want to discuss text, plot, and the ethnic psychology following Japanese erotic culture, I can only say that you have clearly lost some basic capabilities, or your desires.
