The successful duo Eisner and Fellner are on the trail of a conspiracy in the new "Tatort" from Vienna. The task at hand is to investigate the death of a high-ranking official in the Ministry of the Interior, which seems to have had a wide impact. A summer in Vienna. It is hot. Too hot. Bibi (Adele Neuhauser) is jogging through the forest and quite by chance meets a high-ranking official from the Ministry of the Interior. The man is dead a little later. Moritz Eisner (Harald Krassnitzer), who is due to start a long-awaited project at Europol and the EU anti-corruption agency OLAF in The Hague in a few days, decides to take on this case. But is it even a case? The Ministry is pushing to present the cause of death as a simple heart attack. There was apparently no external influence, and the traces of theDoping substances in the blood of the deceased do not prove poisoning.
Although the dead man was feared in the Ministry, he apparently only had friends. He leaves behind an honestly grieving widow, a friendly neighbor and a caring sports doctor. Just as Moritz Eisner discovers the first gaps in the dead man's spotless past, it is announced that he will not get the job in The Hague. However, the exemption he had applied for to go to Holland was granted. Now Moritz Eisner is suddenly rid of the case and his new professional perspective. That doesn't stop him. Quite the contrary: he takes up the fight against apparently overpowering opponents and not even Bibi can hold him back.
