One summer morning, Kiyoshi (Shosuke Hirose) is racing on his bike down the beach. While there, a girl with her clothes torn up is thrown out from a green convertible. This is how he and Sanae (Teresa Noda) first meet. A little while later Sanae's sister comes to pay Kiyoshi a visit, falsely claiming that he participated in her sister's rape. When she shoves him into a car with intentions to hand him over to the police, Kiyoshi finally snaps.
