Four siblings -- Edmund (Skandar Keynes), Lucy (Georgie Henley), Peter (William Moseley), and Susan (Anna Popplewell) -- are sent from their London home to the country estate of an eccentric professor in order to ensure their safety during World War II. The house is very dull, except for a large, ornate wardrobe discovered by young Lucy during a game of hide-and-seek. Venturing inside of it in the hopes of finding a hiding place, Lucy is transported to a snowy alternate universe: a magical world called Narnia. The land is populated by talking animals and ruled over by the benevolent lion god Aslan (voiced by Liam Neeson), but sadly, the world is also in a state of perpetual winter. The white witch Jadis (Tilda Swinton), lustful for power and governed by narcissism, has cursed Narnia with a tyrannical decree that it will always be winter but never Christmas. Now, the children must fight alongside Aslan for the salvation of Narnia, but one of them, seduced by the charisma of the white witch, may choose to fight on the wrong side.
