Na pytlacke stezce

This film in the series begins with a distraught Straka, believing that he will not get to spend time with his grandson because little Vašek is supposed to go to Bulgaria during his summer vacation for a holiday with his parents instead of going back to spend the summer with his grandfather.

Being a tenacious boy, he plans in advance, hiding his suitcase with a neighbor and saving enough money for a bus fare. On the last day of school Vašek picks up his final report, but after that he takes his already packed bag and sets off for the Bohemian Forest without telling his parents. By this time, we already know that the little gamekeeper, knowledgeable and appreciative of the forest just like his grandfather, finds the prospect of spending the summer with his gamekeeper grandfather far more tempting than the seaside and we're happy to see him take this adventure. A friendly bus driver helps to deliver him to the right place and Straka is pleasantly surprised when Vašek appears and is happy to have his grandson at his side again. In the evening, a call comes from Vašek's mother, and the trip to Bulgaria is postponed.

Once again, Vašek and his grandfather have various experiences in the forest together. There is even a poacher on the loose and they work together to hunt him down. The film has more action than the first in the series and it ends with his mother coming a week before the end of summer so they can still have their family trip to Bulgaria. As they are saying their goodbye's, little Vašek receives a cute little gamekeeper's hound of his own announcing "but now I can't go to Bulgaria!"
