1. Nightshade

A confused, 16-year-old girl is found in Dresden at night with a blood-stained scalpel. She reports that her father has kept her and her sister Jana imprisoned in a cellar for life, and that Jana is still there. Detective Winkler believes the traumatized teenager, while Schnabel has his doubts. Investigations and forensic examinations uncover evidence of family bloodstains – and suddenly Amanda herself is under suspicion of murder.
