The castle custodian Král is moving to a new place of work with his wife, son Radek and a five - years old daughter Terezka. Radek takes his cat Líza with him. A fully loaded truck moves through the country which is in spring blossoms, gradually changing into a snow-covered land. Children's imagination creates from real experiences magic stories - a fairy-tale grandpa takes them to a new castle, the children fear a black-horse rider who - as the grandpa and the cleaning lady assert she hates cats.
