Thomas breaks Glader law by entering the Maze to save Minho and Alby, who are trapped overnight. He helps Minho drag Alby back, but Alby is stung by a Griever and falls into a coma. Thomas’s bravery and curiosity make him a hero to some (Newt, Chuck) and a threat to others (Gally). Thomas realizes the Maze’s walls move in patterns – it’s a code. He convinces Minho they can solve it. Meanwhile, a girl (Teresa) arrives in the Box – the first ever female – clutching a note: “She’s the last one ever.” She whispers in her sleep: “WICKED is good.”
Thomas and Minho map the Maze’s movement, discovering the walls form coordinates leading to a hidden door. Gally tries to stop them, revealing he believes the Maze is a punishment they deserve. The Grievers breach the Glade, killing many. Thomas, Minho, Teresa, Newt, Chuck, and a few others race into the Maze at night. They find a sealed chamber in the Griever lair. Inside: a computer terminal. Teresa types a code from her memory, opening a passage to an underground lab. Scientists’ video logs reveal WICKED (World In Catastrophe: Killzone Experiment Department) created the Maze as a test to find brain patterns resistant to a virus that destroyed civilization. The Gladers are immune. As they escape into a desert, Gally appears – controlled by a Griever sting – and throws a knife. Chuck jumps in front, saving Thomas but dying. Thomas kills Gally. They stumble outside to find a devastated world – and men in hazmat suits waiting. maze runner whole movie
