The Upside Down, a place only seen before in psychic visions and nightmares. Will Byers doesn't know what to call the shadowy realm he finds himself in, but he is certain that he is alone and far away from anything close to safe. A strange shrieking monster lurks around every corner and familiar voices drift through the air from the other side. To survive, Will holds onto the lessons he's learned in the camaraderie of his friends, and the hope that he can get back home to his family.
