The full plot of Logan (2017) is a road movie in which Logan, Charles Xavier and Laura run from Transigen, and it ends with the lab children crossing the border after Logan's death.
In 2029 Logan drives a limo and secretly cares for a sick Xavier, helped by Caliban. A nurse named Gabriela pays him to take Laura to a place called Eden near the Canadian border. Gabriela is killed, and Transigen's security chief, Donald Pierce (Boyd Holbrook), hunts for Laura with a squad of cyborg soldiers. Caliban is captured and forced to track the girl.
Logan learns that Laura was grown in a lab from mutant DNA, as one of many children bred to be weapons, and that she is effectively his daughter. That turns a reluctant escort job into a family story. Xavier, Logan and Laura flee across the country and are sheltered for a night by a farming family, the Munsons.
During that night, X-24, a savage clone of Logan made by Transigen, attacks and kills Xavier and the Munson family. Logan buries Xavier, then takes a drug that briefly restores his strength and fights through many of the soldiers.
Logan finds the children from the lab gathered at the border, and the soldiers close in on them. Dr. Rice is killed, and the children overpower Pierce. X-24 stabs Logan, and Laura kills the clone with an adamantium bullet. Logan dies in Laura's arms, telling her not to become the weapon she was built to be. The children bury him, Laura speaks lines from the western Shane, and she turns the cross on his grave on its side into an X before they cross the border.
