In the early 1960s, during the height of the Cold War, a mutant
named Charles Xavier (James McAvoy) meets a fellow mutant named Erik
Lehnsherr (Michael Fassbender). Despite their vastly different
backgrounds -- Charles grew up with a wealthy family, while Erik lost
his parents at Auschwitz -- the two become close
friends. As the world teeters on the brink of a nuclear war, Charles and
Erik with other mutants join forces to save humanity. However, a
situation soon tears the friends apart.
