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.
