Mittlere Reife.

Having trouble coping with school and their teachers, five students are sent to after school detention by principal Seifert. To avoid expulsion they must take extra hours in ethics. It is their last chance. Stressed out with her own exams, the new trainee teacher Mechthild Bremer is not enthusiastic about being assigned to teach this class. Accordingly, the first couple of hours do not run smoothly. The five give her a hard time.
