When Polly vanishes after Uncle Andrew's horrid trick, Digory has no choice but to follow her. Touching the magic rings takes the children into a wood where mysterious pools lead to countless other worlds.

Their adventure opens up the doorway to Narnia -- a new and magical land where animals learn to speak and where trees are able to walk. But Narnia is under threat from the evil Queen, and Digory and Polly have to find the magical fruit that alone can save it.
