The Chronicles of Narnia: The Voyage of the Dawn Treader

Three years after the events of Prince Caspian, Lucy and Edmund Pevensie are staying with their irritating cousin Eustace Scrubb. A magical painting of a ship on the ocean transports Lucy, Edmund and Eustace into an ocean in Narnia. They are rescued by the Dawn Treader. Caspian invites them on a voyage to rescue the seven Lords of Narnia whom his uncle Miraz banished. In the Lone Islands, where people are sold as slaves, Caspian and Edmund are captured and imprisoned while Lucy and Eustace are sold as slaves. Caspian meets one of the lost lords, who reveals that the slaves are not sold, but sacrificed to a mysterious green mist. The crew of the Dawn Treader then rescue the four. The lord, who becomes the new governor, gives Caspian a sword originally given by Aslan. At another island, Lucy is abducted by invisible Dufflepuds who force her to enter the manor of the magician Coriakin to find a visibility spell. Coriakin encourages the crew to defeat the mist by laying the lords' seven swords at Aslan's Table, but warns them that they are all about to be tested. Lucy recites a beauty incantation she found, and enters a dream in which she has transformed into Susan, and neither Lucy nor Narnia exist. Aslan chides Lucy for her self-doubt, explaining that her siblings only know of Narnia because of her. Another sword is recovered from a magical pool that turns anything that touches it (including one of the lost lords) into gold. Meanwhile, Eustace discovers and steals treasure from a dragon hoard. While Edmund and Caspian look for Eustace, a dragon approaches and is driven away from the Dawn Treader. The dragon is Eustace, transformed by the enchanted treasure after succumbing to its temptations. Reepicheep befriends Eustace, and touched by the mouse's kindness, Eustace has a change of heart and becomes useful to the crew. They arrive at Aslan's Table to find three lost lords sleeping. As they place the swords on the table they realize one is still missing. A star descends from the sky and transforms into Lilliandil, a beautiful woman who guides them to the Dark Island, lair of the mist, where they discover the last surviving Lord. Edmund's fear manifests itself as a monstrous sea serpent that attacks the ship. Eustace as a dragon fights the serpent, but Eustace is wounded by the last sword and flies away. He encounters Aslan, who transforms him back into a boy and sends him to Ramandu's island with the last sword. The mist tries to distract Edmund by appearing as Jadis, the White Witch. Eustace overcomes the mist and puts the sword on the table, awakening the three sleeping lords and destroying the mist and Dark Island; Edmund slays the sea serpent and they liberate the sacrificed slaves. Eustace rejoins Lucy, Edmund, Caspian and Reepicheep, and they sail to a mysterious shore before a massive wave. Aslan appears and tells them that his country lies beyond, although if they go there they may never return. Caspian refuses, but Reepicheep is determined to enter, and Aslan blesses him before he paddles beyond the wave. Aslan opens a portal to send Lucy, Edmund and Eustace home, but informs Lucy and Edmund they have grown up and can never return to Narnia. Aslan encourages them to know him in their world by another name, and tells a reformed Eustace that he may return. The three enter the portal and are returned to the bedroom. Eustace hears his mother announcing a visitor, Jill Pole.
