Anyone who claims that you can't live with half a heart should be invited to a fairy tale about a king who once gained a crown in exchange for half his own heart. He gained a crown for part of his heart, but he lost much more – himself, his wife and his child. The prince must undergo difficult trials and fight a witch to save King Oskar and the kingdom...

Carpenter Jakub is preparing a gift for his bride Bára – a carved chest. On the advice of his grandmother, a herbalist, he goes into the forest to find a twig from a magical larch tree so that the chest will blossom. In the nighttime forest, he is helped by the fairy Modřínka, who likes Jakub. However, the proud Bára rejects Jakub, and he almost falls victim to the forest fairies. Who will save him, and who will be his bride?
