The story tells of how Prince Gregor, and his hero, the daring Winfried of England, journey through treacherous land to reach the heathen people of the forest on Christmas eve. When they arrive, Winfried rescues the heathen from an unspeakable evil, destroys the great oak tree where they worshiped their false god, and points to a young fir tree, "the tree of the Christ-child," as the people's new sign of worship, symbolizing laughter, songs, and rites of love.
