Margaret is a shy, pale, middle-class Englishwoman who is reluctantly engaged to her older, twittish neighbor Syl. Both bride- and groom-to-be still live with their mothers in the humdrum suburb of Croydon. However Margaret has been acting strangely ever since a vacation in Egypt, where she stayed with her mother's friend Marie-Claire. She secretly despises Syl, but does not resist when her mother, who has repressed the failure of her own matrimony, insists on marriage for the sake of social convention.
