Postbus X plot
The series is set in Ravenburg, at the editorial office of De Ravenburgse Post, owned by the eccentric Jonathan Hiks, later succeeded by his daughter Ilse Hiks. The Ravenburg Post is a front for the organization 'Postbus X'. People with problems can write a letter to Postbus X in Ravenburg and receive help if necessary. The team consists of Jonathan Hiks, Bodo, Pol and Jessie. The meetings invariably take place in Het Melkhuisje, which is connected to Hiks' office by a hidden elevator. The rest of the editors are not allowed to know anything, which sometimes causes difficulties.
