Last Days (2025) is a biographical drama directed by Justin Lin and written by Ben Ripley. Based on the real-life story of American missionary John Allen Chau, the film follows his increasingly dangerous attempt to reach the isolated Sentinelese people of North Sentinel Island. At the same time, the story follows an investigator trying to prevent the mission from turning into a tragedy.
Starring Sky Yang, Radhika Apte, Ken Leung, Naveen Andrews, Toby Wallace and Ciara Bravo, the movie combines elements of a character-driven drama, adventure thriller and true-story film. It premiered at the 2025 Sundance Film Festival before receiving a U.S. theatrical release on October 24, 2025.
Last Days (2025) Story
The story centers on John Allen Chau, a 26-year-old American Christian missionary who becomes determined to reach North Sentinel Island in the Andaman and Nicobar Islands. The island is home to the Sentinelese, an Indigenous community known for maintaining an extremely isolated existence and resisting contact with outsiders.
John believes that reaching the island and sharing his faith with its inhabitants is his life's mission. Despite the obvious dangers surrounding the journey, warnings from others and the legal restrictions protecting the island's inhabitants, he continues pursuing his objective.
Alongside John's journey, the film introduces investigators in the Andaman Islands who become increasingly concerned about what could happen if he succeeds in reaching the island. This parallel storyline gives the film a second perspective on the events and places John's personal convictions against the responsibilities of those attempting to stop him.
Rather than presenting the story simply as an adventure, Last Days focuses on John's beliefs, his relationship with his family and the increasingly complicated consequences of his decisions.

Sky Yang's Performance
Sky Yang carries much of the film as John Allen Chau, a character whose determination becomes increasingly difficult to separate from his recklessness. His performance attempts to show both the sincerity behind John's beliefs and the emotional isolation that influences his choices.
The role is particularly challenging because the film does not present John as a straightforward hero or villain. Instead, Yang has to portray a young man convinced that he is pursuing something meaningful while simultaneously making decisions that place himself and others in serious danger.
Radhika Apte and the Supporting Cast
Radhika Apte provides an important counterpoint to John's perspective through her role as Meera. Her character represents a more grounded view of the situation, particularly as authorities try to understand John's intentions and prevent further harm.
Ken Leung is also effective as Patrick, John's father. Their relationship gives the film a personal dimension beyond the central mission. The conflict between a father's expectations and his son's religious convictions helps explain some of the emotional pressures surrounding John's decisions.
Naveen Andrews, Toby Wallace and the remaining supporting cast help expand the story beyond John's individual experience and reinforce the film's different perspectives on the events.
Justin Lin's Direction
Last Days is an unusual project for Justin Lin, whose career is strongly associated with large-scale action films, particularly his work in the Fast & Furious franchise. Here, the director takes a much more restrained approach while still using elements of suspense and adventure.
Lin creates tension from the uncertainty surrounding John's journey rather than relying primarily on conventional action. The isolated setting, dangerous environment and knowledge of the real events give many scenes an uneasy quality because the audience understands that the situation is moving toward a tragic outcome.
However, the direction has also attracted criticism for trying to balance too many elements at once. Several critics felt that the movie's multiple storylines and shifts in time weaken its central character study.
Last Days Review: Does the Movie Work?
Last Days is a difficult film to evaluate because its subject matter is inherently compelling, but its approach to that material is uneven.
The strongest aspect is the uncomfortable moral tension at the center of the story. The movie does not simply ask whether John was right or wrong. Instead, it explores how personal conviction can become dangerous when it overrides warnings, laws and the autonomy of people who have deliberately chosen isolation.
The film also benefits from its natural setting. The remote environment gives the story an unsettling atmosphere, while the contrast between the outside world and North Sentinel Island reinforces the central conflict between intervention and isolation.
Where the movie struggles is in its characterization. Several critics argued that the screenplay does not explore John's psychology deeply enough to fully explain why he becomes so committed to his mission. The narrative also moves between different characters and periods of John's life, sometimes making the story feel scattered.
Rotten Tomatoes currently lists the film at 32% from 31 critics, while its audience score is considerably higher at 69% from more than 100 verified ratings. Metacritic lists a score of 43/100 based on 11 critic reviews, indicating a mixed critical response.
What Is Last Days Really About?
At its core, Last Days is about conviction and its consequences. John sees his mission as a spiritual responsibility, while the people around him increasingly view his actions as reckless and potentially harmful.
The film also raises questions about cultural boundaries. The Sentinelese have deliberately remained isolated from the outside world, and the story highlights the ethical problem of attempting to impose outside beliefs or contact on a community that has repeatedly rejected it.
Another important theme is the difference between intention and consequence. John's intentions may be sincere from his own perspective, but the film asks viewers to consider whether good intentions can justify actions that place other people at risk.
Last Days Ending Explained
Spoilers ahead.
The ending follows the tragic real-life outcome that the film has been building toward. John Allen Chau proceeds with his attempt to make contact with the Sentinelese despite the warnings and dangers surrounding the mission.
His decision ultimately leads to his death after he reaches North Sentinel Island. The tragedy is especially disturbing because the film has already shown the various warnings and obstacles that could have prevented the final confrontation.
John's body was never recovered. The ending therefore does not provide a conventional resolution in which every detail of the character's fate is explained. Instead, the uncertainty surrounding the aftermath reinforces the real-world tragedy at the heart of the film.
The ending also gives greater weight to the investigators' attempts to intervene. Their concern is not simply about John's personal safety; the situation involves protecting an isolated Indigenous population from outside contact and preventing a potentially violent encounter.
Is Last Days Based on a True Story?
Yes. Last Days is based on the real-life story of John Allen Chau, an American Christian missionary who traveled toward North Sentinel Island in 2018 in an attempt to make contact with the Sentinelese people.
The screenplay was inspired by Alex Perry's Outside magazine article about Chau. The film dramatizes real events, so some scenes and character interactions are presented as part of a narrative feature rather than as documentary footage.

Is Last Days Worth Watching?
Last Days is most interesting as a morally complicated true-story drama rather than as a conventional adventure movie. The real events provide a naturally powerful foundation, and Sky Yang's performance gives the central character enough complexity to keep the story engaging.
However, the film's scattered structure and uneven character development prevent it from reaching the depth that its subject deserves. Viewers looking for a tightly constructed thriller may find the pacing inconsistent, while audiences interested in the ethical and religious questions surrounding Chau's story may wish the screenplay explored those issues more deeply.
For viewers interested in true stories, religious conviction, cultural boundaries and difficult ethical questions, Last Days offers plenty to discuss even when its dramatic execution feels uneven.
