Young Oxford University graduate Charles Xavier (James McAvoy – Starter For Ten) is asked by CIA Agent Moira MacTaggert (Rose Byrne – Insidious) to aid her with a conspiracy case that involves mutants. It’s something so potentially threatening it could even ignite a third world war. Along the way Charles meets Erik Lehnsherr (Michael Fassbender – Centurion), a man looking for the person responsible for his mother’s death at a Nazi concentration camp. After finding out that they are after the same man, Charles and Erik team up and begin assembling a special team of mutants who can challenge Sebastian Shaw’s (Kevin Bacon - Footloose) bid for world domination. But as their lines are drawn for battle it becomes clear that Erik and Charles have very different ideas on the future of mutant evolution.
