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.
