Prairie Clarke and her best friend Selma have a wonderful three weeks at the Chautauqua. They live in a tent where Selma is chief cook; they go in for self improvement, have an eventful moonlight ride on the lake, meet some celebrities, one of whom invites them to dinner at the hotel and paints Prairie's picture in her own gingham dress. Then as a grand climax, they take part in the cantata, Esther. A story of a generation ago in South Dakota which will bring back amusingly nostalgic memories to adults, but which, in the characters of the girls themselves, has enough vitality to find good friends among today's girls.
