A cheerful series about the adventures of a group of children living in the countryside, produced in a Polish-West German co-production (the pictures were taken in picturesque locations in Dąbrowa nad Czarna, as well as in sand caves near Sulejów). The biggest attraction of the area is the historic water mill, which becomes a great place for fun for an amused crowd. As is usually the case in the countryside, its equal inhabitants are - next to people - animals. No wonder the little heroes become friends with them. And so days go by together. Almost each of them brings a new, amazing and unexpected adventure. The child's imagination makes even ordinary events take on the flavor of fairy tales and mystery.
