Twenty-year-old Atsushi and his seventeen-year-old girlfriend Mari arrive in Tokyo from the suburbs with plans to marry despite their parent's objections but they are soon pulled into the city's dark underside. Atsushi meets Miki, a fading adult video (AV) actress, and gets introduced by the veteran Yoshiya to the occupation of "scoutman", recruiters who ply the streets trying to convince young girls to join the AV industry. Meanwhile, Mari, looking for work, runs into Kana who initiates her into the business of selling tickets to swinger's parties. The young couple continue to fall deeper into the seductions of Tokyo's sex industry and away from each other.
