The third and final chapter of the Maze Runner series sees Thomas (Dylan O'Brien) and the rest of the Gladers attempt, once and for all, to take down the evil WCKD organization by penetrating Last City, a labyrinth controlled by the group. His goal is simple: To save children being used as test subjects by WCKD, who hope to find a cure to a virus killing off humanity. It leaves Thomas with the choice to either save his friends and those being held captive, or potentially the entire world.
Production on this sequel was delayed a year after O'Brien suffered major injuries when he was run over by a vehicle during the filming of a stunt sequence in March 2016. Filming resumed nearly a year later in February 2017, and officially ended in June 2017.
Here's the final trailer for the movie, coming soon in cinemas 25 Jan 2018:
