Mrs. Harschmann tells the third year's class that they will be represented by a young trainee, Gabriele Griffel, in the next few weeks. She is very nervous and uncertain whether she is up to the task. But the girls are looking forward to the new teacher and give her a warm welcome! Unfortunately, this reception is so extreme that Mrs. Griffel only gets more nervous. Moreover, Mrs. Harschmann has told her to teach relentlessly and with a hard hand. This meets with little enthusiasm among the girls. The relationship between the girls and the teacher is getting worse and worse. On a trip to the forest the situation escalates.
