A Czech agricultural student, Šimon Plánička, arrives at the small South Bohemian town of Hoštice, and joins the local JZD (agricultural co-op) with the intention of trying out his experiment regarding the "Milk yield of cows in regards to a cultured environment". He runs into difficulty with the directorship of the JZD, but he finds them eager to help once they hear he's the son of the local agricultural commissioner, as his last name is also Plánička. Blažena Škopková is given the task of finding out how things are looking. However everything is complicated by the jealousy of Blažena's boyfriend Venca.

The local farmers' cooperative organized a trip to Italy, in which the Škopkovci took part. They went there at the invitation of the Italian agricultural cooperative, whose employees are going to visit Hoštice in return. In addition to the sights, the goal of the tour was also an excursion to a modern Italian cowshed. After returning home, Hoštice and its inhabitants are waiting for a "great approach to Europe" - they plan to improve the neglected village by building a nudist beach. However, as it usually happens, the Italian delegation appears at the least convenient moment. Strangely enough, they like the cooperative's neglected economy so much that they propose to preserve it as an open-air museum...
