Wendy is the British guest of a French couple and the daughter of the man who saved the host's life during World War II. Living with the couple is their 20-year-old son and a 12-year-old nephew whose parents were killed in an automobile accident. The father and son both try to seduce the attractive guest. The young boy retreats into his own world and dreams of being taken back to Britain by Wendy in this romantic drama. The mother spends her time bleaching her hair and is seemingly uninterested in anything that goes on with her family at the beachfront villa. Meanwhile, Wendy and the younger boy develop a fondness for each other, while his aunt and uncle fail to understand his needs.
