As reports of people born with extraordinary genetic abilities spread across the globe, fear of mutants begins to divide humanity. Hidden within a peaceful academy, renowned telepath Professor Charlotte Xavier has devoted her life to protecting young mutants while teaching them that humans and mutants can one day coexist. Her first generation of heroes the X-Men risk everything to defend a world that increasingly fears them. At the same time, Charlotte's former friend Erik Eisenhardt, known as Magneto, believes peaceful coexistence has already failed. Having witnessed humanity's cruelty firsthand, he forms the Brotherhood of Evil Mutants, determined to ensure mutant survival through strength rather than compromise. As anti-mutant sentiment grows under the influence of the charismatic Reverend William Stryker, two young mutants discover they are caught between Xavier's dream and Magneto's revolution. The future of mutantkind will depend on which vision prevails.
