Parasomnia

13-year-old Talia surprised a murderer shortly after his deed and thus becomes the most important witness for commissioners Winkler and Gorniak. Unfortunately, the teenager can no longer remember anything, because Talia has developed a psychological self-protection since her mother's accidental death seven years ago: If she sees something that overwhelms her emotionally, her consciousness represses what she sees and changes it into a fictional reality that seems less horrible to her. Since then she has also tended to parasomnia: sleepwalking. While Gorniak and Schnabel try to follow all the other traces, Talia begins to trust Winkler and lead the commissioner into "her world". Together, the two succeed in overcoming Talia's fears and overcoming her trauma. Thalia is now able to provide the decisive clue that leads the investigators on the trail of a serial killer.
