A successful chemist is forced to return his honeymoon vouchers to Greece. His fiancée has bought a dog for her hyperactive daughter against his wishes. Thanks to a conspiracy between the girl and the dog, the whole family ends up on vacation in the middle of the Šumava "wilderness." At first, the alternative vacation seems idyllic. All the plans of the ambitious father and caring mother gradually fall apart when the daughter and the dog meet someone who understands them. And that person has friends at the guesthouse where the family is staying. Of course, the mother and her fiancé find these people a little crazy. But the girl and the dog are perfectly happy with them. The life full of restrictions and obligations that the girl has led so far is becoming a thing of the past. None of the adults who find themselves in their vicinity can be sure that their lives will not change, whether they want it or not.
