S1·E1 The Lion, the Witch and the Wardrobe (1)

It's 1940, and the Pevensie children, Peter, Susan, Edmund and Lucy, have been sent to stay in the countryside where they will be safe, away from the war. Their home for the duration is a huge rambling mansion that the children cannot resist but explore, during which Lucy stumbles across an old wardrobe which hides a magical secret.
