There’s an evangelical strand of Hasidic Judaism - Chabad-Lubavitch - spreading across the world. THE RABBI GOES WEST focuses on one such Chabad rabbi, 34-year-old Chaim Bruk, who moved from Brooklyn to unlikely Bozeman, Montana, to bring his brand of Judaism to the American West. Part of his mission is to place a mezuzah, an encased prayer offering, on the doorpost of every Montana Jew. That’s less than 2,000 families spread across a state fourteen times larger than Israel.

As he travels across this “big sky” landscape, Chaim confronts a terrifying neo-Nazi threat, and also objections to his proselytizing from other rabbis, both Reform and Conservative. While he is beloved by his congregants, others fear that Chaim will put up Chabad centers everywhere in Montana. Will Chaim succeed, and at what cost, in his Chabad mission?
