They open a door and enter a world Narnia ... a land frozen in eternal winter ... a country waiting to be set free. Four adventurers step through a wardrobe door and into the land of Narnia — a land enslaved by the power of the White Witch. But when almost all hope is lost, the return of the Great Lion, Aslan, signals a great change ... and a great sacrifice. Four English schoolchildren find their way through the back of a wardrobe into the magic land of Narnia and assist Aslan, the golden lion, to triumph over the White Witch, who has cursed the land with eternal winter.
