The two youngest Pevensie children, Lucy and Edmund, are staying with their odious cousin Eustace Scrubb while their older brother, Peter, is studying for an exam with Professor Kirke, and their older sister, Susan, is travelling through America with their parents. Edmund, Lucy, and Eustace are drawn into the Narnian world through a picture of a ship at sea. (The painting, hanging neglected in the guest bedroom in which Lucy was staying, had been an unwanted present to Eustace's parents.) The three children land in the ocean near the pictured vessel, the titular "Dawn Treader", and are taken aboard.
