Maze Runner: The Scorch Trials doesn’t hit Hall H until Saturday, but after a special screening of the first film at San Diego Comic-Con, 20th Century Fox showed off the first 30 minutes of the sequel.

In case you need a quick refresher, the events of The Maze Runner went down in a place called The Glade, a large grassy area surrounded by four gigantic walls separating Thomas (Dylan O’Brien) and the other Gladers from The Maze, a massive labyrinth that’s patrolled by vicious creatures called Grievers. They manage to escape, but it turns out, The Maze is only the start of what Wicked has planned for them. Thomas and co. are eager to get answers, but in order to do so, they’re going to have to trek through The Scorch first.
