A historical film that takes place on the eve of the thirty year war combines aspects of fairy-tales with historical dramas, fencing with a child heroes who find themselves in great dangers. We are in the year 1611 and mercenaries that had previously invaded Czech lands now have to withdraw before the Hungarian king's army. In this chaos a magical bottle, that fulfills the owner one single wish, appears among some fugitives - however after the fulfillment it has to be sold for half it's price to a new owner. The director Ludvík Ráža has created an attractive and surprisingly cruel film aimed not only at young viewers.
