The pony hotel has just been opened, but so far no guests have arrived. Dick gets Ralf to design a brochure about the hotel. The girls and Ethelbert then lead the village children on horseback to Lübeck, where they all distribute the brochure - not knowing that Dalli has added some embellishments to the text. An orphaned boy wins a two week stay at the hotel. Luckily, paying guests are coming now, too. Most important among them is Dr. Westkamp, boss of a travel agency. Unfortunately, he keeps himself very much to himself. Quite unlike a certain Fräulein Gisela, who much to Dick’s dislike seems to have set her cap upon Ralf. All is happily resolved when it turns out that Gisela is Westkamp’s secretary. Westkamp offers a contract to Jochen and a job to Ralf, and from now on, the Immenhof never has to go without guests anymore.
