In the last part of the trilogy from the beautiful Bohemian Forest known as umava, the focus is once again on the gamekeeper Straka and his grandson Vaek. Sharing adventures involving poachers, badgers and battling storms, the two have formed a strong bond and now view each other as heroes. Once again, Vaek has a memorable summer vacation.
Previously we saw Vaek with almost a naively enraptured view of nature, mainly because of his age, his grandfather's protection and his innocence. The primary lesson in this conclusion is that it's time for grandfather to teach him about understanding the life and laws of nature, and his innocent becomes replaced with a more sympathetic view when Vaek realizes that nature must be protected at all costs. Of course, being the cute little boy he is, this causes a whole series of comic situations while teaching the viewers about the importance of environmental protection.
