The third part of the franchise, Maze Runner: The Death Cure (2018), follows the young hero Thomas, who sets out on a mission to find a cure for a deadly disease known as Flare.
Thomas knows he can not trust Wicked, but they say the time of lies has come to an end, that they have gathered everything they can from tests and that they now have to rely on Gladers with completely restored memories to help them with their last mission. It depends only on Gladers to complete the plan for healing Flare disease with a voluntary final test.
What Wicked does not know is that something happened that no tests or variables could have predicted. Thomas remembered much more than they thought. And he knows he can not believe any word of what Wicked says. The time of lies is over. But the truth is more dangerous than Thomas could ever imagine.
Thomas and the surviving Gladers are preparing to confront Wicked for the last time, struggling to find a cure for the deadly disease that destroyed most of the world. Friendships and loyalty will be tested, and the fight against Wicked will also determine who will eventually survive.
