Dora, a lazy and evil woman, is in love with her servant, Hannes. Hannes, however, loves her sister-in-law, Margareta. When Dora learns about this, she vows revenge against the couple.

Markéta and Honza are a loving and beloved royal couple. The cunning princess Eufrozína beguiles Lucifer with her charm and, with the help of seven-league boots, flees from hell with her father to reunite with King Brambas and deprive Honza of his throne. Honza's evil sister Dora also takes advantage of his absence on a campaign against the enemy and sneaks into the castle, where she almost kills Markýta and her newborn son, just so she can win Honza for herself. This time, however, the lovers are supported by Kujbaba, Hnipírka, Valihrach, the wise godmother, a pair of devils, Lucifer himself, a three-headed dragon with a little dragon, and other characters.
