It is World War II, and the Nazis have taken over Poland. In this story, three citified children of Resistance fighters have taken refuge in the mountains, and they manage to hook up with three local youngsters. All six of them are being hunted by the Germans, and they are also being looked for by an adult who wants to take them to greater safety. Along the way, the children occasionally put on spontaneous theatricals.
