On 25 April 1605, the knight Milota was killed by the royal armourers while escaping from the castle of Temice. However, the robbed treasures were not found in his possession. Almost 400 years later, Jindra, Tomas and eighteen-year-old Alena spend their holidays at the castle with their grandfather, the castellan. The castle needs repairs, but there is no money for them. Tomas and Jindra decide to find Milot's treasure, which could help the castle. The visitors are guided by Alena and two temporary workers, Roman and Petr.

At a roadside inn, the wandering knight Dan and his squire Vítek meet two offended former ministers of the Forest Kingdom. They complain that the young princess Jelena, who recently took the throne, spends her time hunting with her female companions, but hates men and does not want to marry—and with a capricious woman on the throne, the country will soon come to a bad end. This intrigues the young men—they have never met Amazons before—and so they set off for the capital city.
