Honoria, the daughter of Sara and Gerald Murphy, who invented the literary "summer on the Riviera" in the 1920s, is used to her parents' endless parties with such luminaries as Scott and Zelda Fitzgerald, at their splendid house at Cap d'Antibes. When sheltered and unsophisticated Ida visits for a summer, Honoria becomes both her mentor and tormentor, as well as her role model and, finally, her friend.
