Awakening in an elevator, remembering nothing of his past, Thomas emerges into a world of about thirty teenage boys, all without past memories, who have learned to survive under their own set of rules in a completely enclosed environment, subsisting on their own agriculture and supplies. With a new boy arriving every thirty days, the group has been in "The Glade" for three years, trying to find a way to escape through the Maze that surrounds their living space (patrolled by cyborg monsters named 'Grievers'). They have begun to give up hope when a comatose girl arrives with a strange note, and their world begins to change with the boys dividing into two factions: those willing to risk their lives to escape and those wanting to hang onto what they've got and survive.

The second chapter of the epic "Maze Runner" saga. Thomas (Dylan O'Brien) and his fellow Gladers face their greatest challenge yet: searching for clues about the mysterious and powerful organization known as WCKD. Their journey takes them to the Scorch, a desolate landscape filled with unimaginable obstacles. Teaming up with resistance fighters, the Gladers take on WCKD's vastly superior forces and uncover its shocking plans for them all.
