Set in the 1940s, the ballet begins when four siblings, Lucy, Edmund, Susan, and Peter, visit the Old Professor and discover an empty room with a large wardrobe. Young Lucy opens the wardrobe door and steps in; her brother Edmund follows her and they find themselves in a wintery forest of another world. A series of adventures begin that include an umbrella-carrying faun, an evil White Witch, a beaver couple, a kind-hearted lion, and myriad other characters. They, along with the siblings, engage in a mystical battle of good over evil. Although the White Witch traps Narnia in a seemingly endless winter, the promise of spring arriving brings beauty and hope to the holiday season.
