Two prostitutes have been murdered in Tokyo. Yuriko had been working as a prostitute all her life, starting while still at school, where her stunning beauty compensated for what she lacked in intellect. Kazue worked for a blue-chip company. She chose to walk the streets at night where she hoped to get noticed. How and why did this tragedy occur?

In a suburb on the outskirts of Tokyo, four girls drift through tedious summer school classes. Then Toshi's next-door neighbour is found brutally murdered and the girls suspect Worm, the neighbour's son. They become drawn into a treacherous vortex of brutality and seduction which rises from within themselves as well as the world around them.
