The Pevensie childrenPeter (William Moseley), Edmund (Skandar Keynes), Susan (Anna Popplewell), and Lucy (Georgie Henley)face a perilous mission and a greater-than-ever test of their faith and courage. Thirteen hundred years of Narnia time have passed since their last visit, but only one year in their normal reality. Although the White Witch (Tilda Swinton) is gone, making only a brief appearance in the movie, the realm is ruled by a cruel tyrant, King Miraz (Sergio Castellitto), and Aslan (voiced by Liam Neeson) has been missing for over a thousand years. With the help of Prince Caspian (Ben Barnes), the four children embark on a journey to find Aslan and restore magic and glory to the land.
