Four children are sent to the country to escape wartime London. One morning, Lucy scrambles inside an old wardrobe… a moment later she finds herself in Narnia, a snow-covered land in the grip of the Wicked White Witch where it is always winter. Any human seen in Narnia is at mortal risk! Lucy slips back through the wardrobe, and recounts her tale to her brothers and sister. They all go back to Narnia when they least expect it, and find it even more real and frightening than Lucy had described.

The four children soon discover that only Aslan can protect them from the terrifying danger that threatens to destroy them all…
