Before you know it, they're on the run again, brimming with confidence and turning into a formidable group of rebels, and in search of the mythical Right Arm group of revolutionaries, who live in the distant mountains.
To get there, the Gladers must battle terrifying zombies, survive electrical desert storms and seek help from outlaws who would happily sell them back to Paige.
The premise isn't as intriguing as the original, and again we're drip-fed information, but there's a real sense of urgency and desperation. Thomas must make snap decisions to save his friends but, no matter what the Gladers do, evading Paige seems impossible.
Though not quite The Hunger Games, Maze Runner: The Scorch Trials isn't far off.
Director Wes Ball keeps the ball rolling at a cracking pace, veers into horror territory with gruesome zombie action and, though the characters don't really develop, elicits genuine performances from his young cast.
With a neater, more satisfying ending this time, Ball delivers, and leaves us curious about what's in store for the Gladers in 2017's third instalment.
