18-year-old Vibeke Henningsen is a student at a large modern school for girls and boys. She is an only child, and her parents, who are both self-employed, have not devoted the necessary time to Vibeke's upbringing. She was born with a combative and difficult character, and when she is demoted from 12th grade to 11th grade after a probationary period, she directs her hatred toward the school's most beloved teacher, Associate Professor Poulsen, whom she directly accuses of refusing to allow her to continue in 12th grade.
