Logan is a centuries-old mutant whose skeleton is laced with indestructible adamantium, the result of brutal experimentation. Armed with retractable claws, enhanced senses, and a regenerative healing factor, he left the mutant strike force Team X three years ago under circumstances he has tried to put behind him. When mutants begin disappearing at the hands of Bolivar Trask, a billionaire industrialist commanding a cybernetically-enhanced private army known as the Reavers, Logan is drawn back to his former team. To stop Trask and rescue the missing mutants, he must confront the violent past he thought he had escaped.
