Five Keys to Blaník

After the assassination of Prince Wenceslas, young Radim is sent from Prague to the countryside for safety. Here he must not only learn to take care of himself, find his place in a completely new world, but also find his way to his grumpy grandfather. It gradually becomes clear that Radim' s grandfather is part of a secret plan that has to do with the mysterious Blaník hill, the lost golden treasure, but also with the murdered Prince Wenceslas. Will Radim have enough strength to protect his grandfather' s fortress and at the same time complete a plan that goes beyond anything he could have imagined up to that point?
