The fifth installment in the brutal series about attacking high school students cycling to school in the countryside. This time, the setting is a port town, where high school students are ensnared. An innocent girl walking along the embankment is given a standing doggy style on a beach with a clear blue sky. A kind girl who shows him the way is taken onto a fishing boat and forced to give a blowjob. He returns the kindness shown to him with evil, placing a dark bookmark on a page of their youth.
