The Gladers are finally free of the maze and the sinister reapers which stalk its ever-changing corridors. But now they face a new challenge in navigating the unforgiving desert terrain known as "The Scorch" as they continue to search for liberty and safety. Many of the original cast reprise their roles including Dylan O'brien, Kaya Scodelario and Thomas Sangster while Aiden Gillen and Giancarlo Esposito join the cast as the malignant WCKD enforcer, Janson, and the hardened rebel leader, Jorge, respectively. After escaping the maze, the surviving Gladers are taken into a facility run by WCKD - whom were already revealed to be the corporation behind the mazes in the first film - where they are greeted by scientists, medical experts and the site's manager, Janson. Sensing that his group are in danger, Thomas leads them in an escape and the Gladers find themselves in the midst of an expansive desert where civilisation has crumbled into the dirt it once sat atop. Leaving safety behind them, the group will now have to face greater threats as they are pursued by WCKD, drifters and the ominous "cranks". Maze Runner: The Scorch Trials - Saturday 10:35pm on Channel 4.
