His parents had reported him missing. Now her worst fears are coming true. Mark is frozen. The police had discovered the boy in the cold room of the "Fringshof". Mark's father, Bernd Bürger, can hardly be contained in his hatred. Regardless of whether it was murder or just an accident, he is certain that the farm owner, Iris Findeisen, is to blame for his son's death. But why should the game and fowl dealer want to kill an innocent child?Inspectors Ballauf and Schenk are skeptical. Obviously, Iris Findeisen was not well tolerated in the small town on the outskirts of Cologne. The attractive businesswoman is also a thorn in the side of Mark's grandmother Helene and those responsible at the neighboring rifle club. Only Mark's mother Nadja Bürger does not want to comment on this. After the death of her son, she is in shock. A second murder occurs shortly afterwards.
