STORY LINE (in english):
A dead man floating 'in the water is found in the Danube River in Austria. It is the second such case within a few months. Like the first man, this man was also single and had withdrawn all his cash before he came to Vienna.
At the same time, there are increasing numbers of reports from single women who have fallen for a marriage swindler in Vienna. The older man, who always pretended to be noble, put the women in a small hotel and robbed them after they passed out.
Vienna police senior inspector Marek, and his assistants district inspector Wirz and inspector Berntner take over the investigation. They find out that the men were poisoned with a substance that is only produced in Johanna Hassmann's small company in Vienna.
When questioned, she admits that a bottle of the poison was stolen some time ago, which she reported to the police. She had her colleague Maria Hillmann under suspicion, but she had left the company shortly after the allegations. When asked by Berntner, their landlady Eleonore Heller said that Ms. Maria Hillmann had moved a long time ago. Marek and the assistants talk about how the bodies found in the river long after their murders and recently after their murders must have different original locations on a map.
In the meantime, the single Grete Bändler arrives in Vienna and is expected by the distinguished Udo von Kahlreuth. He pretends to have little money, but shows interest in marrying Grete, for whom he has reserved a small hotel room. They both go to the Wurstelprater (an amusement park and section of the Wiener Prater in the Leopoldstadt area of Vienna) and Udo sees' her 'the next evening in' her 'hotel Kaiserhof hotel room with much friendly greeting and hugging. He gives her chocolates. He picks up her purse and quickly asks if she should deposit all the money in the bank. As they talk, he says: "his future is grey". "No, because its a future with me" she quickly says back. After a while, it lead to major illness in Grete, and he disappears with her money.
At the time, Wirz has just arrived in the hotel Kaiserhof's lobby, looking for a hotel with neon signs opposite the description of the women who had been betrayed. The maid reports that strange noises have come from Grete's room, and Wirz finds the woman passed out. The night porter is arrested on suspicion as an accessory to the' attacker, though he begs and begs not to be taken.
Maria Hillmann, who is suspected of stealing poison is later in the morning found dead' on the banks of the Danube River. 'She only died the day before, as the studies show, and she was also poisoned.
Meanwhile, Marek's other police assistant Berntner meets with the Yugoslav restaurant operator Mirko Kolarovic who a few weeks ago had a couple in his restaurant, and after a while the man showed signs of intoxication. Kolarovic even feeds assistaant Berntner. Kolarovic promises to contact Berntner if he should see the woman again.
