In this biography that opens with her farewell tour, Joan Baez takes stock in an unsparing fashion, confronting often painful memories and opening up about her history with mental illness, her family, drugs, ageing and questions of guilt and forgiveness. For the first time on record, she speaks to her relationship with Bob Dylan, how she used her fame to launch his career, and the pain of their later estrangement. The film interweaves diary entries and Baez’s own illustrations with extensive conversations and backstage moments from the tour.
