In the final installment of the Maze Runner trilogy, Thomas (played by Dylan O’Brien) and his friends are determined to rescue their friend Minho from the Last City, a WCKD-controlled stronghold. The Last City is a heavily fortified and walled-off city where WCKD conducts experiments on immune individuals to find a cure for the deadly Flare virus.
As the group infiltrates the Last City, they face various challenges and confrontations with WCKD forces. Throughout the film, Thomas learns more about his past and his connection to the creation of the Maze trials. It is revealed that he was part of a group of kids who were experimented on to find a cure for the Flare virus.
In the climactic battle, Thomas confronts Ava Paige (played by Patricia Clarkson), the leader of WCKD, and Janson (played by Aidan Gillen), a WCKD operative. The group manages to rescue Minho, but casualties occur along the way.
The film takes a tragic turn when Newt (played by Thomas Brodie-Sangster), one of Thomas’s closest friends, succumbs to the effects of the Flare virus. Newt, who is not immune to the virus, begs Thomas to end his suffering, forcing Thomas to make a heartbreaking decision.
As the group escapes the Last City, they encounter a massive wall of the infected Cranks, and it becomes clear that the fight against the Flare is far from over. The survivors make it out of the Last City, and the film concludes with a hopeful but uncertain future. Thomas decides to continue the fight against WCKD and find a safe haven for the immune survivors.
The movie ends with a scene showing Thomas and his friends discovering a paradisiacal refuge, indicating a new beginning for those immune to the Flare virus. The final scenes suggest that the survivors have a chance to rebuild and establish a life beyond the control of WCKD.
Overall, “Maze Runner: The Death Cure” concludes the trilogy with a mix of action, emotion, and closure, bringing an end to the epic journey of Thomas and his friends.
