Elijah is building a fort in the woods behind his new home when he is greeted by a strange girl named Iris. At first she helps him work, but she soon insists on a game of hide-and-seek. So Elijah searches and searches for Iris . . . until it begins to get dark.

Just as he yells that he has to go home, Iris suddenly appears, angry about being left alone in the woods. It’s only the first troubling omen as Elijah grows more uncertain if he wants to spend time with his hide-and-seek friend.
