Young Prince Caspian of Narnia wonders and dreams about the old days of Narnia when animals talked, and there were mythical creatures and four rulers in Caer Paravel. But his uncle and aunt don't like to hear him thinking of such things, and plan to murder him and take his throne. Caspian's tutor, Dr. Cornelius manages to save him, and not only teach him about the old ways, but bring him into the real Narnia and introduce him to the real Narnia. But Caspian's plight is desperate, and he must use the legendary horn to call help from another world: Peter, Susan, Edmund, and Lucy.

Lucy and Edmund are sent back to Narnia, along with their cousin Eustace, to assist Caspian on a voyage. Along their journey the children battle dragons and sea serpents, and sail across a golden lake to reach the edge of the world.

Prins Caspian kalder Lucy, Edmund, Peter og Susan til Narnia, for han har nemlig brug for deres hjælp. Sammen med Aslan, den mægtige løve, besejrer de Kong Miraz i en spandende kamp for at genskabe Narnias storhed og pragt. Flere år senere havner Lucy og Edmund endnu engang i Narnia sammen med fætteren Eustance. Denne gang skal de ledsage Caspian på en rejse, hvor de skal finde syv forsvundne adelsmænd. Eventyret fører til sammenstød med både drager og havuhyrer.

Le prince Caspian appelle Lucy, Edmund, Peter et Susan à Narnia dans son temps le plus pénible du besoin. Dirigés par Aslan, le Grand Lion, les enfants aident la jeune Caspienne à vaincre le Roi Miraz corrompu dans une bataille spectaculaire.
