Documentary about the American folk revival, the milieu from which the nascent Bob Dylan emerged in the early 1960s and whose crucible was the Newport folk festival. In 1963 it provided the perfect platform for Dylan, under the patronage of Pete Seeger and Joan Baez, to be acknowledged as the principal voice of folk music at the age of just 22. Other stars of the time such as Baez, Seeger, Peter Paul and Mary, Judy Collins, Muddy Waters and Mahalia Jackson are also featured.
