The Innsbruck forensic pathologist Dr. Simone Katzian, who discovered dubious machinations and manipulations by colleagues, is killed. Since she has previously informed her friend Dr. Haller about her knowledge, she also becomes the target of the murderer and almost dies in a car accident. The investigations of the SOKO focus primarily on a cardiologist congress that is currently taking place in the city and its figurehead Dr. Moritz Thonhauser, who has a complicated relationship with his mother, a luminary in his field. Kroisleitner takes great care of Dr. Haller and finds out that she has concealed some things from him.
