Two young people, Hidenori and Sunako, are on the run from the law following Hidenori’s killing of his mother. The two manage to hitch a ride in a passing ice-cream van, but Sunako is assaulted by its driver while bathing in a stream in a forest. They escape through the trees, eventually ending up in a secluded wooden cottage where they hide out, eking out a feral existence by raiding neighbouring gardens. With Hidenori still in a state of shock, Sunako eventually breaks the communication barrier using her body, seducing him in a bathtub full of floating ripe tomatoes. It is a turning point in their relationship, and Hidenori then becomes the sexually dominant partner in this strange relationship. One day, Hidenori plunges a knife into his stomach, forcing the pair to leave their makeshift haven and seek help in the big city.
