Laura Fischer has a session with a psychologist. The session begins with the young woman telling that after two years of successive rapes of female students riding bicycles in the woods near the campus of the college where she studied, student Emma Machielsen has formed a committee with Josien Schippers, Marieke Kopermode, and Bonnie Javoer to discuss a possible solution with the dean. However, the dean claims that he has no budget to improve the security and can only afford to provide three buses for the students. The girls decide to bike through the woods together in convoy, but when Marieke is late, they leave her alone on the campus. She decides to cross the woods alone, and the serial rapist rapes her. Her friends decide to investigate the crimes by themselves and they prepare a list of possible rapists, leading the group to a tragic consequence.
