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.
