In 18th century Bohemia, the mercenary troops of a cruel duke roam the countryside. A cap maker who defends himself against injustice is thrown into prison. His ten-year-old son tries to free his father with the help of his friends of the same age and a magic cap, but the duke's henchmen are soon after the magic cap.
