In the year 2029, mutants are on the brink of extinction, with no new mutants having been born in 25 years. James “Logan” Howlett (Hugh Jackman), formerly known as Wolverine, spends his days working as a chauffeur in Texas.
His healing factor has faltered and, as a result, his body has aged greatly. Logan lives with mutant tracker Caliban (Stephen Merchant) in an abandoned smelting plant across the Mexican border, where they care for Professor Charles Xavier (Patrick Stewart), who is suffering from Alzheimer’s disease which causes him to lose control of his telepathic abilities to destructive effect. Xavier’s seizures cause a debilitating pain for Caliban and Logan, which only subsides when Logan administers tranquilizer to Xavier to bring him under control.Logan is behind payments on his stretch limousine and is being harassed to make payments for $40,000 asap. Caliban also finds that Logan is carrying around an Adamantium bullet, making him wonder if Logan is contemplating suicide. Caliban knows that Logan’s body is not healing, and his eyesight is also failing, and yet Logan would not talk about it with anyone.One day, Logan is approached by Gabriela Lopez (Elizabeth Rodriguez), a nurse for biotechnology corporation Alkali-Transigen, who wants him to escort her, and an 11-year-old girl named Laura (Dafne Keen) to a place in North Dakota called “Eden” (The last know refuge for Mutants).
Gabriela offers Logan $ 50,000 to driver her & Laura up there. Logan needs the money, so he can buy a boat and keep the Professor on the ocean and limit the impact of his devastating seizures.
Gabriela is very injured and bleeding from the arm and she says that Transigen wants to kill her. She says that Laura is her daughter.After reluctantly accepting the job from Gabriela, Logan goes back to Xavier to pick up a few supplies for the trip. Logan drives to Gabriela’s motel & discovers that she has been murdered. Logan returns to Mexico in his limo and Caliban finds that Laura also came with him, hiding in his boot.
Logan, Xavier, and Laura narrowly escape from her killer, Transigen’s Cybernetically enhanced chief of security Donald Pierce (Boyd Holbrook), and his enforcers, the Reavers. Logan sees that Laura is a capable fighter herself. She has Adamantium claws in her hands and feet and has healing powers as well. Laura helps Logan fend off Donald and his enforcers and allows them to escape in Logan’s limousine.
Caliban is captured and forced to use his powers to track them when Donald exposes Caliban to sunlight and his skins starts to burn.Logan and Xavier learn that Laura is one of several mutant children Transigen was breeding using DNA samples from several mutants for the “X-23” project. The children were born in captivity in Transigen labs and were raised there. There mutant genes were enhanced over a period of time and then harvested.
Upon completion of the “X-24” project, the children were deemed obsolete and were to be Euthanized. Gabriela helped several children escape from the Transigen compound before smuggling Laura, who is revealed to have been created from Logan’s DNA, across the border.
Xavier convinces Logan that Laura is his daughter for all practical purposes.Logan reaches Oklahoma City and buys a new car with the money he got from Gabriela as his limousine is totaled. While waiting for new tires to be installed on his car, he finds that a set of coordinates written on an envelope given by Gabriela, match the ones on a Marvel’s comic book.
The Reavers catch up with them in Oklahoma City, but Xavier suffers a seizure and telepathically freezes everyone in their hotel, allowing Logan to kill the attackers before injecting Xavier with a suppressant and escaping.
While on the highway, the trio helps farmer Will Munson (Eriq La Salle) and his family after a traffic incident (An auto truck goes a bit off track and pushes Logan’s & Munson’s vehicles off the highway). Xavier asks Logan to help Munson to get back his horse, who had escaped the trailer due to the mishap. The Munsons invite them over for dinner, and they accept under the guise of being a Trigenerational family.
When a nearby pipe springs a leak, Logan and Will leave the house to fix it.While Logan is gone, Xavier recalls a telepathic seizure he had in Westchester, where he inadvertently killed several civilians and X-Men. He expresses his guilt to a person he thinks is Logan, but which is actually X-24, a feral clone of Logan with a limited healing factor. X-24 stabs Xavier through the chest before slaughtering the Munson family.When Logan returns, Xavier succumbs to his wound and Caliban sacrifices himself by setting off two grenades to destroy the Transigen van in which he is being held captive. Logan engages X-24, which gains the upper hand, but Will drives a car into X-24 and impales him. He shoots X-24 before dying, allowing Logan and Laura to escape.After burying Xavier, Logan passes out from exhaustion. He wakes up in a clinic that Laura had driven him to but refuses to get further treatment and wants to abandon the trip. Laura convinces him to complete it, and they arrive at Eden, a safe haven run by Rictor (Jason Genao) and the other Transigen test subjects that managed to escape.Logan learns that the children plan to journey across the Canadian border and decides to part ways with them. However, when the children are intercepted by the Reavers, Logan intervenes. Dr. Zander Rice (Richard E. Grant), the head of Transigen whose father had been slain by Wolverine during his escape from Weapon X, pacifies Logan and reveals that the destruction of mutant kind is due to a genetic dampener forged by his company, which hid it among food and drinks.
Horrified, Logan shoots Rice dead before Pierce releases a regenerated X-24, who engages Logan. The children wipe out the remaining Reavers before overwhelming and killing Pierce with their powers.Logan and Laura fight X-24, with Rictor using his seismic powers to help them. However, X-24 brutally impales Logan on the branches of a fallen tree. While X-24 is trying to finish Logan, Laura shoots X-24 dead with an Adamantium bullet Logan had been keeping since Weapon X.Mortally wounded, Logan tells Laura not to be the weapon she was made to be before dying in her arms. Laura and the other children mourn his death and hold a somber burial, marking his grave with an “X”, honoring him as the last of the X-Men before continuing on their journey across the border.
