King Edmund, Queen Susan and Mr. Tumnus the Faun are visitors in the country of Calormen, where Prince Rabadash wants Susan to marry him. Thinking that Shasta is the missing Prince Corin of Archenland, Narnia's ally, Edmund scolds the boy for running off and making everybody worried sick of him. The Narnians escape, thanks to Tumnus' cloever plan, which leads Rabadash to make his father agree that they should take Narnia by invading Archenland.
