The Lion, the Witch and the Wardrobe

In 1940, four siblings - Peter, Susan, Edmund, and Lucy Pevensie - are among many children evacuated from London during World War II to escape the Blitz. They are sent to the countryside to live with professor Digory Kirke. Exploring the professor's house, Lucy finds a wardrobe which doubles as a magic portal to a forest in a land called Narnia. At a lamppost oddly located in the forest, she meets Tumnus, a faun, who invites her to tea in his home. There the faun confesses that he invited her not out of hospitality, but with the intention of betraying her to the White Witch. The witch has ruled Narnia for years, using magic to keep it frozen in a perpetual winter. She has ordered all Narnians to turn in any humans ("Sons of Adam" or "Daughters of Eve") they come across. But now that he has come to know and like a human, Tumnus repents his original intention and escorts Lucy back to the lamppost.
