A boy wakes up in an elevator with no recollection of his name, where he comes from, or where he is. As he emerges from the earth, he finds himself in a community of boys, living in a glade. As the boy slowly starts unearthing memories, such as his name, Thomas, he also finds out more sinister things from the other boys about the place he's landed. and for three years they've been looking for a way out. And now it's up to Thomas to find that way. But the road isn't going to be easy, as any who dares enter the maze finds himself hunted by the Grievers.
