“Stralsund – Schattenlinien” – The fourteenth case leads the team of investigators from Stralsund into the dark past of a children’s home in GDR times.
A yacht explodes on the Strelasund. Britta Böhring, née Hanssen, but her husband, Jan Böhring, son of a hotelier family, is killed.
Investigator Nina Petersen notices during her investigations that Annegret Böhring deals with her loss as if she had already known about the death of her son. The reason for the explosion is a remotely detonated explosive device – a targeted attack? Even worse for Mr. and Mrs. Böhring, because they were supposed to be on the ship.
What no one knows: Annegret Böhring, the former head of the children’s home Richard Dorn and the ex-Stasi man Martin Krenn are being anonymously blackmailed. But those threatened remain ironclad in their silence to the investigators and their families and commission the Stasi man to “take care of the matter”.
Nina Petrsen finds out that Annegret Böhring was a doctor in the notorious children’s home “Kiefernhain” in GDR times under her maiden name Anna Engels. After the reunification, she, like the other blackmailed people, has built up a new existence in Stralsund.
When an unknown person tries to kill the injured Britta Böhring in the hospital, the situation comes to a head. Stein finds a film in Britta’s cell phone – recorded shortly before the explosion. Hidde discovers light signs on it, which he can identify as a military Morse code. Karl Hidde knows the password from the military: diving company.
The investigators are certain that they have stumbled into a vendetta that will lead them into a suppressed chapter of the GDR: “Kiefernhain” was one of the worst children’s homes in the GDR. A few of the former children from Kiefernhain live in Stralsund: among them Dirk Wegener and Mike Voss.
Nina Petersen, Seibert and Hidde operate on a psychological minefield.
