A new trailer for "Maze Runner: The Scorch Trials" takes viewers deeper into the mysterious, desolate world of the Scorch, a desert-like wasteland beyond the Glade that's teeming with its own challenges. Was it worth risking everything to escape in the first place?



That's the question on the minds of Thomas (Dylan O'Brien), Teresa (Kaya Scodelario), and the rest of their teenage crew, as they go head-to-head with the shady WCKD organization, and its murky plans for them. Janson (Aiden Gillen) tries to persuade Thomas and co. that they're making a mistake in venturing outside the Glade, but it seems like it's all just a bunch of mind games designed to keep them in their place.



Or is it? As we see in the trailer, the Scorch appears to be every bit as grim as foretold, and there's danger lurking around seemingly every corner. The Gladers team up with a band of resistance fighters to take down WCKD, but it doesn't come without great personal cost.



"Who's side are you on?" Janson asks Thomas at one point in the clip. The division between the two camps may not be so black and white after all.



"Maze Runner: The Scorch Trials" also stars Thomas Brodie-Sangster, Giancarlo Esposito, Barry Pepper, Lili Taylor, and Patricia Clarkson. It's due in theaters on September 18.
