The boy Thomas (Dylan O'Brien) woke up in the elevator. Strangely, he couldn't remember anything except his name. When the elevator opened, he came to a strange place called "the glade". It is surrounded by tall stone walls, where many boys, including Newt (Thomas Sangster), Chuck (Blake Cooper), Mino (Ki Hong Lee), etc., are trapped in a maze, and there is also a group of huge monsters threatening them outside the wall. One day, the elevator sent them a girl, Teresa (Kaya Scodelario), who was the first girl to come here. After that, the maze gradually began to change, and everything fell into chaos. Thomas and Teresa decided to embark on the road to crack the maze together to find out the chilling secrets behind the maze. The film is adapted from the first book of the dystopian science fiction trilogy of the same name written by James Dashner.
