Based on James Dashner's popular young adult novel, this adaptation takes us inside a mysterious place known as The Glade, an area that is enclosed by a massive maze, which houses a number of deadly monsters known as the Grievers. Dylan O'Brien plays the newest addition to this group of kids known as Gladers, who have no memory of why they were brought to this place.

Take a look at this new behind-the-scenes footage to see how these cast members bonded together on the set of The Maze Runner, arriving in theaters Septmeber 19.

The story follows a boy named Thomas who wakes up in a strange place called the Glade with no memory aside from his first name. The Glade is an enclosed structure populated by other boys, and is surrounded by tall, stone walls that protect them from monsters called Grievers that live in the Maze, which surrounds the walls around the Glade.

Every day, some of the kids who are Runners venture into the labyrinth trying to map the ever-changing pattern of walls in an attempt to find an exit.

As soon as Thomas arrives, unusual things begin to happen and the others grow suspicious of him. The Maze seems familiar to Thomas, but he's unable to make sense of the place despite his extraordinary abilities as a Runner.

When the first girl arrives in the Glade, she brings a message that she will be the last one to ever arrive in the Glade, as the end is near.
