The Glade newcomer Thomas (Dylan O'Brien) is introduced to "The Circle" by Gally (Will Poulter) in a new clip from The Maze Runner, which also includes a brief introduction by author James Dashner. Based on the best-selling book of the same name, this story follows Thomas, who is mysteriously transported to a place known as The Glade, which is populated by a number of young men his own age, enclosed by a stone maze that features deadly monsters known as the Grievers.

Watch as Thomas goes toe-to-toe with the much-larger Gally in hand-to-hand combat, as the rest of the "Gladers" look on in this scene from director Wes Ball's adaptation, arriving in theaters September 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.
