The Mupfer gang is again forced to admit defeat by the Schmutzer gang, and the Mupfers then begin to stir up trouble. If the bosses - Meier and Ferri - do not come up with a brillant idea soon, they will be toppled. Ivonka Pivonka, a 12-year-old girl who is inclined to snoop, is on the trail of three robbers of postal money transports. Unfortunately, Ivonka is more curious than she is careful. After being caught, she is locked up at gentle-natured Kitty's apartment. Meier and Ferri read about Ivonka's disappearance and decide to help her escape. With the help of Liese, Ivonka's best friend, and Alice and Aline, two elderly ladies, they begin to track down the postal robbers.

After suffering a severe head injury on the job, criminal investigator Tommy Wehrschitz is being suspended – for his own good. In order to deal with the changes in his life he decides to go to southern Burgenland, to sell property he inherited from his estranged father.

A male body was found floating in Lake Triestach near Lienz in East Tyrol. According to the autopsy, Konrad Kofler, Tyrol's Minister for the Environment, had a relatively low blood alcohol content and apparently drowned.

After 16 years, Sabine travels back to her home village. The occasion is a class reunion. She wants to return to Vienna that very evening. She has only come anyway because things are still not settled between her and her childhood sweetheart Leonhard. The joy of their reunion is overshadowed by the disappearance of his daughter. The events awaken a sense of déjà vu in her. In addition, she learns of the suicide of her former best friend. She directs her suspicions towards her former teacher, the village's great patron, Dr. Körbler. "Körbler loves children", she writes on a note, which she anonymously passes to Leonard. The girl had tutored with Körbler before she disappeared. Sabine obviously has good reason to suspect the seemingly harmless old man.
