Prince Caspian and the Voyage of the Dawn Treader

Prince Caspian calls Lucy, Edmund, Peter, and Susan back to the magical land of Narnia in his most harrowing time of need. Led by Aslan, the children help young Caspian to defeat the corrupt King Miraz, and restore Narnia to its full glory. Years later, Lucy and Edmund are sent back to Narnia, along with their insufferable cousin Eustace, for yet another perilous journey. This time the children assist Caspian on a voyage to rescue six lords of Narnia banished under Miraz's reign. Along their journey the children battle dragons and sea serpents, and sail across a golden lake to reach the edge of the world. (official distributor synopsis)
