Twenty-year-old Sora Shiina is a fashion college student who moved to Tokyo, working part-time jobs to pay her tuition while striving toward her dreams. Cheerful and friendly, she's popular among both guys and girls. But one day, she suddenly wakes up to find herself imprisoned in an unfamiliar house. A man who has been stalking her is there, violating her body without any communication, driven purely by primal instincts and taking her repeatedly. Her once smooth-sailing life changes completely from that moment onward.
