Inspector Frank Thiel is investigating a spectacular murder case. While playing at the Aasee, children discovered a headless corpse. Shortly before her death, the young woman must have consumed vast amounts of red wine and truffles. The autopsy report by forensic pathologist Prof. Karl-Friedrich Boerne is unequivocal: The circumstances are the same as in the Rohrbach murder that caused a stir in the 1950s, which was never solved and is still considered an unprecedented judicial scandal today. The pressure on public prosecutor Wilhelmine Klemm and her team is correspondingly great. First, the identity of the corpse must be clarified. Inspector Thiel is investigating a missing persons report by student Laura Schott .
Is the body your friend Solveig Helmhövel? The bookseller Sigbert Helmhövel and his sister Monika are surprised. You think Solveig is on holiday in Madeira. Meanwhile appears with Dr. Oleg Buykov a very influential Ukrainian businessman on the scene. Even the Federal Ministry of Economics warns the investigators to exercise extreme discretion. The personal description of the dead from Lake Aasee fits his wife exactly, the traveling salesman puts it on record. Is the Russian mafia involved here? In fact, a little later Buykov identified the corpse as Olga Buykova. But Thiel remains skeptical. Then a second murder occurs.
