As the boy slowly starts unearthing memories, such as his name, Thomas, he also finds out más sinister things from the other boys about the place he's landed. The boys are held prisoners within the center of a gigantic maze, and for three years they've been looking for a way out. Now it's up to Thomas to find that way, but the road isn't going to be easy, as any who dare enter the maze finds himself hunted por the Grievers.
