Mostly set in fictional land of Narnia, filled with talking animals and mythical creatures that is ruled by the evil White Witch. Four children are relocated to a large, old country house following a wartime evacuation. The youngest, Lucy, visits Narnia three times via the magic of a wardrobe in a spare room. Lucy's three siblings are with her on her third visit to Narnia.
In Narnia, the siblings seem fit to fulfill an old prophecy and find themselves adventuring to save Narnia and their own lives. The lion, Aslan, gives his life to save one of the children; he later rises from the dead, vanquishes the White Witch, and crowns the children Kings and Queens of Narnia.
