Kreuzeder was once a successful commissioner, but now he rarely solves a case. After more than 20 years in the service, he just wants to retire as quickly as possible and leave everyday life in the homicide squad in Lower Bavaria behind. Kreuzeder is of the opinion that humanity is coming to an end anyway, so he prefers to get drunk in the tavern and flirt with the waitress Gerda Bichler there instead of going about his work.

In order to save her mountain guesthouse from ruin, Sopie plans to build a glass extension with a pool as an attraction. She comes up with this saving idea when her best friend Verena visits, who brings her brother Jan with her and who draws the plans for it.

A summer's day on Lake Chiemsee: children discover the body of a man on a sailing boat. Inspector Hattinger and his colleagues from the Prien police start investigating. Shortly afterwards, a second body is found: The author Annette Kaufmann has been murdered in her vacation apartment.

A property on Lake Ammersee including inventory plus 183,000 euros and 47 cents - Fanny Steininger is over the moon about this inheritance! A certain Walter Jeromin bequeathed it all to her. Allegedly her biological father, but the 60-year-old slob, who has just quit her job as a train attendant, more or less ignores this. After all, her dad, who once made a name for himself as the white sausage king (and regularly appears in her daydreams as an advisor), died back in 1969. However, Fanny has to fulfill one condition in order to inherit her estate, as her junior boss Tristan from the law firm Hackenbusch & Söhne informs her: She is to apply for guardianship of her supposed half-brother Elias, who lives with Asperger's syndrome.

Unfortunately, Fanny can only enjoy her unexpected wealth for a short time. The tax office asks her to pay a hefty inheritance tax. Because of the valuable property, she has to pay far more than she was bequeathed in cash. Debts again - and her "crazy" half-brother Elias on top of that? She would like to get rid of him as quickly as possible.
