Das jüngste Geißlein.

In the Black Forest, Detective Friedemann Berg discovers a frightened nine-year-old girl (Eliza) hiding in a clock case. Shortly afterward, her father's body, weighed down with stones, is found in a forest lake. His colleague Franziska Tobler and a child psychologist investigate, while Berg tries to help the selectively mute child overcome her trauma and find the missing mother.
