Sliding, skiing, snow forts, snowball fights, in short, winter is the right season for the children from the village under the Šibeničák hill to have fun. Their leader has always been Zrzek, the son of the local undertaker. But then Myšák, whose father had become the chairman of the agricultural cooperative, moved into the village, and he pulled all the boys to his side, especially because he could take the boys on the horses his father sometimes lent him. Proud Zrzek left the group rather than submit to Myshak. Only his friend Barbora remained faithful to him, helping him catch birds, especially the proverbial black raven.

In the village cemetery, the funeral of a married couple - victims of a car crash - is ending. The relatives unscrupulously take away the facilities of the dead people's little cottage, totally ignorant of the fate of eight-year old Ruda, whom the childless couple took from a children's home and adopted. Fortunately, an elderly lonesome uncle named Tony remains in the empty cottage and decides to take care of the boy, nicknamed Münchie after Baron Münchhausen for his wild imagination.
