At long last, King Dalimil and Queen Eliška have produced an heir, Princess Růženka. Consumed with envy, Eliška’s sister Melánie casts a curse: On the day Růženka turns seventeen, she will prick her finger and fall into a deep sleep together with the entire kingdom.

Czech nobleman Petr Vok of Rozmberk (Milos Kopecký) is no longer so young, but his amatory adventures continue to arouse the envy of men and the indignation of respectable ladies. In his "female retinue" at the chateau in Bechyne he has twelve comely girls, but he still manages to seduce the miller's wife and the maid. Lord Vok is in great financial difficulties. His elder brother Vilém advises him to marry a rich woman. Petr surprises him by announcing his intention to marry the very young Katerina of Ludanice.
