Moses Zaltzman is a beloved Hasidic rabbi in a dusty desert town. When his congregation is violently attacked, police quickly arrest a young white nationalist who threatened them in the past, but Rabbi Mo thinks the troubled teen may be innocent. Since no one else will investigate, Mo becomes the detective. As the bodies pile up, he finds himself bonding with the teen, learning how to arm himself to face the threat, and fearing that he won't pull the trigger if he has to worse, that he will.
