Twenty-one-year-old Akihito Takaba is a young freelance photographer who takes pride in his work and seeks to get a major "scoop". After he takes photographs of the business dealings of crime lord Ryuichi Asami, Asami kidnaps and rapes him, beginning a relationship between them as they find themselves continually drawn to one another. Liu Fei Long, a rival Chinese boss who blames Asami for his father's death, takes an interest in Takaba, as well, seeking a way to get revenge.
