Rabbi Abraham Joshua Heschel was one of the most influential scholars of the 20th century. Author of important religious works including The Prophets, Heschel was a leading activist, mentor to the civil rights movement, critic of the Vietnam War, champion for Soviet Jewry, and pioneer of interfaith dialogue. Drawing on archival footage and rarely-seen interviews with a diverse group who knew and were influenced by Heschel, this comprehensive documentary provides a fitting portrait of the one of the most important Jewish figures of the last century.
