Musician, civil rights campaigner and activist Joan Baez has been on stage for over 60 years. For the now 82-year-old, the personal has always been political, and her friendship with Martin Luther King and her pacifism have shaped her commitment. In this biography that opens with her farewell tour, Baez takes stock in an unsparing fashion and confronts sometimes painful memories. She not only shares her successes but also speaks openly about long-standing psychological problems and therapies, about family, drugs, aging and questions of guilt and forgiveness. The film interweaves diary entries and a wealth of partly previously unseen archive material with extensive conversations with Joan, as well as backstage moments from the tour.
