Narnia is in trouble! All the magical creatures and Talking Animals have been forced into hiding by an evil king. Fortunately, young Prince Caspian escapes in time to lead the Old Narnians in the fight for their freedom.

But when the battle goes badly, Caspian blows an enchanted horn. Suddenly Peter, Susan, Edmund and Lucy Pevensie are pulled back into Narnia from England, where they had returned after defeating the evil White Witch. In a race against time and with the aid of the Great Lion, Aslan, they join Caspian and his army in a battle to restore peace throughout Narnia.
