Logan, an ancient mutant bearing an indestructible adamantium-reinforced skeleton, has spent three years attempting to distance himself from Team X and the trauma of his augmentation. His superhuman abilities—retractable claws, heightened senses, and rapid cellular regeneration—make him a formidable force, yet he seeks only solitude from his violent history. When the industrialist Bolivar Trask and his mechanically-augmented private military force, the Reavers, begin systematically abducting mutants, Logan finds his exile forcibly interrupted and discovers his former comrades in danger. Drawn reluctantly back into action, he must confront both Trask's technological army and the ghosts of his own past to save those he abandoned.
