Alfred Dreyfus, a German-Jewish captain serving in the French Army, is falsely accused of treason and made a scapegoat for military espionage in an act of institutional anti-Semitism. Sent to prison, he becomes a cause célèbre for the novelist Émile Zola, who dubs it the "Dreyfus Affair." Eventually, Dreyfus is pardoned when the military cover-up is made public, and he returns to France. But his name is forever tarnished by the accusations of treason.
