A romantic fairy tale about faithful love and how difficult it is to fulfill it. "I have never seen two sisters who love each other so much," sighs King Stephen when he discovers his one true love, the orphaned knight's daughter Anička, in an old fortress in the woods where he wanders while hunting. And indeed, Katka stands faithfully by her stepsister's side, even though fate, thanks to her stepmother's curse, prepares the most difficult trials that a young, beautiful girl can encounter. And so, in the final song, the fairy queen can sing not only to the lovers from the fairy tale, but also to all of us: "Every love overcomes evil, every love interprets God, the flower that stands alone withers, so I have love for you..."
