The Maze Runner

A teenage boy wakes up inside an underground elevator with no memory of his identity, and greeted by several male youths in a large grass area, called the "Glade," enclosed by tall stone walls. The "Gladers" have formed a rudimentary society, and each assumes specialized tasks. The boy learns that a vast Maze surrounding them is the only way out. During the day, designated Runners search the Maze for an escape route and return before nightfall when the entrance closes. After a competitive fight with Gally, the boy remembers his name is Thomas. The next day, he is attacked by Ben, a Runner who has been stung and left delirious by a Griever, one of the techno-organic creatures that roam the Maze at night. Ben is forced into the Maze and left to die as a direct consequence of his actions, along with there being no cure for his condition. Alby, the leader, and Minho, the lead Runner, later retrace Ben's steps inside the Maze the following morning. Minho reappears late in the afternoon dragging Alby, who has been stung, but are unable to reach the closing entrance in time. Thomas runs into the Maze to help, which leaves all three trapped. Thomas lures a Griever into a closing passageway, which causes it to be crushed. The three manage to survive the night and return the next morning.
