'The Believer' is based on the true story of a Jewish neo-Nazi. By day he gives anti-Semitic speeches, raises money for a neo-fascist movement and plans to bomb synagogues. By night he studies Torah and teaches Carla Hebrew while she tempts him with plans to light candles and say Sabbath prayers. For a brief moment, Danny has everything he wants. He is a Jew and a neo-Nazi at once, not reconciling them, but living the impossible contradiction.
