The Last Righteous Man portrays the story of the Abuhazira family, a Jewish-Moroccan dynasty that has been leading Jewish-Moroccan and Israeli communities for two centuries. Through the story of Baba Sali and his younger brother Baba Khaki, the film reveals the story of a Moroccan aristocratic rabbinical family and its transformation into a leading family in Israel. The film moves between Morocco and Israel, from the great wave of immigration from Morocco to present-day Israel, through the biography of Baba Sali and Baba Khaki, and the public activity of the second generation: Rabbi Baruch Abuhazira and Aharon Abuhzira, who took the reins of leadership, shaping Israeli culture, society and politics.
