The new owner Štěpán (Jakub Prachař) arrives at the castle at the foot of the Krkonoš Mountains with his fiancée, the beautiful countess Blanka (Dominika Morávková), and his younger brother Adam (Jan Nedbal). There is another new visitor in the mountain town, the ethnographer Jiráček (Ondřej Sokol), who collects local legends and is amazed that the local people still believe in Krakonoš. Štěpán's carriage knocks down a passing girl, whom Adam helps and she falls in love with him. Will Liduška's (Leona Skleničková) love for Adam come true? What mystery does the painting at Hůrka Castle hide and what terrible thing once happened in the mountains? Who will decipher the mysterious marks of the Italian book? And who is Krakonoš (David Švehlík) and what is his biggest secret?
Unfortunately the movie The Secret of Krakonoš is not yet available on HBO Max.
