English teacher Astrid has been living with her former pupil Klara for ten years. When Astrid invites her superior, principal Wolfram Balderkamp, to her home to continue a conversation she started at school about an explosive 'incident' that took place during their school trip to Trier, Klara reacts - as is unfortunately confirmed in the course of the plot - justifiably nervously: what will happen if he remembers her as a former pupil at his school?
Under the pretext of "protecting" Astrid, Balderkamp would rather discuss the "incident" with her in private and not at school. It's about the accusation of sexual harassment that 16-year-old Ellen's father made against Astrid over the phone. On the school trip, Astrid is said to have drugged her pupil Ellen, who according to her own statement "suddenly felt dizzy" although she had hardly had anything to drink, with knockout drops and touched her indecently.
Is Astrid wrongly accused of abusing a minor? Or is the student trying to convince her father that her crash was not the result of binge drinking, but that her condition was caused by outside influence?
