THE VOYAGE OF THE DAWN TREADER (BBC Series)

Lucy and Edmund Pevensie are sent to spend the summer with their horrid cousin Eustace, and all three are pulled magically into a painting of a boat and wind up next to the real thing in the sea off the coast of Narnia (why this happens, as far as we can tell, is a mystery, unless it is meant to merely be "Aslan's Will"). A year, again, has passed for the Pevensies, and three years in Narnia (endless fun can be had by trying to make some kind of sense in the way time works in the books - a year in our world can equal three years, 50 years or a thousand years in Narnia, depending); King Caspian is setting out across the sea to find the seven Lords loyal to his father who were sent away from Narnia on a fool's errand by Miraz. Lucy and Edmund (and Eustace, who spends some time transformed into a dragon as apparent punishment for his arrogance) join in the quest.
