Poklad na Sovím hrádku(2004)

Every castle hides some secret. This is no different in the fairy tale Treasure at Owl Castle. Deep underground at Owl Castle lies a treasure guarded by a golden owl. The treasure has remained hidden from the human world for centuries. Only the fairy-tale gnomes Kilián and Damián and their friend Emilka the owl knew of its existence. And if these gnomes had not happened to meet the children Honzík and Andělka, the treasure would have remained hidden forever. But gnomes are talkative creatures, and children are very curious. So it wasn't long before the stingy and greedy duchess from the nearby castle found out about the treasure. The wealth left to her by the duke wasn't enough for her; she wanted more and more. So she decided to get the golden treasure at any cost. This put not only herself but also the children in dangerous situations.
