The kingdom of Henry I is broke, and the ghost of his stingy grandfather Maximilian haunts the place. The king and queen lose their nerves, leave, and leave the castle and its problems to their son, the young prince Jindřich. He is left alone with everything, with only his eccentric but loyal servant Ámos. The kingdom could be saved very quickly. A messenger from the Association for the Protection of Free Princes visited the castle, but Ámos is used to following orders to the letter. When he learns that the Association pays free princes 5,000 gold coins to protect them from battles with dragons over capricious or proud princesses, the messenger is already gone. The desperate prince orders his servant to be vigilant and ensure that he does not fall in love and marry. He believes that the messenger will return. However, instead of the messenger, the beautiful princess Pavlínka arrives at the castle, whose nanny predicted that she would find happiness, love, and wealth there!
