Logan, the man code-named Wolverine, is haunted by his unknown past. The feral mutant with the fast healing factor and superhuman senses of smell, sight and hearing has no idea how he mysteriously acquired a skeleton and claws made from an unbreakable metal alloy called Adamantium. As he wanders the country soul searching and looking for answers, a gigantic, ferocious mutant brawler named Sabretooth stalks him. The savage hunter with nearly identical powers to Logan is obsessed with defeating his enemy in a no-hold barred fight to the finish. It will take all of Logan's will and courage to defeat his monstrous opponent when these two feral fighters finally come face to face as Professor Xavier's X-Men battle Magneto's Brotherhood.
