In this documentary, Michael Apted revisits at age 35 the same group of Britons which he previously interviewed at ages 7, 14, 21, and 28. The subjects are from a variety of economic and social groups. Through the interviews, viewers have quite literally watched the youngsters grow up to become adults. The series of interviews creates a sociological document of postwar Britain and a moving portrait of the mystery, surprises and disappointments of growing up.
