1,300 years in Narnia after the Pevensie siblings left, Caspian, a Telmarine prince and the rightful heir to the throne, is informed by his mentor Doctor Cornelius that his uncle, Miraz, is plotting to kill him and seize the throne for himself and his newborn heir. Cornelius gives him Queen Susan's ancient magical horn, instructing him to blow it only at his greatest need. Caspian flees into the woods where he encounters two Narnian dwarfs, Trumpkin and Nikabrik, and a talking badger named Trufflehunter, and blows the horn to summon help.
