Logan, a former Canadian special forces soldier who compromised himself, is going through difficult times: alcoholism, memories of a failed mission in North Korea and a dark secret known only to him alone. A petty criminal in hiding after being charged with murder, he is kidnapped by a group of scientists and taken to a research complex in the Canadian Rockies. There, under the guidance of the brilliantly gifted, unscrupulous and enigmatic Professor, Logan begins the process of an agonizing transformation into Weapon X - an unstoppable, immortal destroyer with retractable steel claws and the ability to heal any wounds.
