Set in the never-sleeping city of Ikebukuro, this film portrays the hidden lives of young gyaru girls. Despite having boyfriends, these girls calmly spread their legs for other men for various reasons—some seek money, others crave sex, while some are driven by stress from home or school. Shockingly, some runaway girls expose their youthful bodies as a substitute for shelter, or as revenge after a fight with their boyfriend. Their actions give rise to the figure known as the Ikebukuro Bitch.
