Did Trockland have to die because he found out about illegal arms deals? The ZERV seized large quantities of NVA weapons on the military premises that were officially considered scrapped. Peter Simon and his employees guard the military equipment, which is equipped with tracking transmitters, because they want to track down the arms dealers. Simon and Karo Schubert learn that Gärster knew Karo's father from the KoKo days and that Karo's mother had a romantic relationship with Trockland. Simon is overwhelmed by his colleague's personal involvement and doesn't want to continue working with her. Karo Schubert makes another discovery: her father had a fatal accident five years ago - on the day of his death there was a meeting between Trockland, her father, Gärster and two other men. Trockland had taken photos. What was the meeting about and where are the photos? The ZERV takes on a case of forced adoption in the GDR: Roland Merker is looking for his daughter. The then 3-year-old was taken away from him after a failed attempt to escape and put up for adoption. Merker was sentenced to eight years in prison. To this day he does not know where his child is.
