When he undertakes the daunting task of saving his father's ailing fruit trees, the young Prince Iwanich becomes enamored by a dream lady, Militza, who he cannot speak of, for he is bound to secrecy. Praised as a hero for saving his father's trees, the prince flees in search of the woman and her palace. They become betrothed, but one day, Militza is called away on duty, and leaves the prince with one request: there is one room in the house forbidden to him. But burning with curiosity, the prince opens the door to the room and unleashes a hurricane of unfortunate events. He is instantly transported to a wood where he becomes a witch's servant, and his fair Militza comes under the control of an evil magician.
