Finally live out the feeling of revenge against Prof. Boerne and murder Boerne - the scientist and professor Harald Götz (Peter Jordan) can hardly think of anything else. He doesn't hide that from his psychotherapist, Dr. Corinna Adam (Oda Thormeyer). While Boerne has just landed the funding for a prestigious research project, Götz has been on his own in the laboratory for years. He searches feverishlyfor a medicine for his seriously ill wife Martina. But after she is found shot dead in her wheelchair, the case is clear for Inspector Thiel: Harald Götz is an urgent suspect. Especially since neighbors saw him fleeing the house. In the evening, Götz gains access to Professor Boerne's ceremony in a restaurant. Boerne urgently needs the support of Commissioner Thiel - more than ever.
