The movie is set in the period covered by the last chapter of The Lion, the Witch, and the Wardrobe during the reign of the four Pevensie children as Kings and Queens of Narnia. Though three of the Pevensies appear as minor characters in The Horse and His Boy, the main characters are two children and two talking horses who escape from Calormen and travel north into Narnia. On their journey, they learn of the Prince of Calormen's plan to attack Archenland, and warn the King of Archenland of the impending strike.
