A young beauty sacrifices love and happiness to become an international celebrity.

Diana Scott, an Italian princess by marriage and a famous member of the jet set, is being interviewed by a reporter from a woman's magazine at her Italian villa. She relates the story of her life and how she came to be what she is. ... Born into an upper-middle-class family, she is spoiled as a child because she is so beautiful. Disregarding advice, she is married very young to an equally immature young man. This first marriage fails, and Diana, a model, starts to live her own life in the world of London television and advertising. She meets and falls in love with television journalist Robert Gold, who is so infatuated that he leaves his wife and children for her. But Diana, trying to further her career as a model, abandons him temporarily for an executive, Miles Brand, who finds her a small part in a horror film. After the opening of the film Diana tells Robert that she is pregnant; both are initially pleased and want the child, but soon Diana decides to have an abortion. Taking the matter very lightly, she tells Robert she never got any satisfaction from sex. While recovering at her sister's country home, she is bored and returns to Robert. Once more, however, she leaves him for Miles, who takes her to Paris to experience the wild bisexual parties of his crowd. When Diana returns to London, Robert walks out on her. Diana takes up with homosexual photographer Malcolm, who takes her to Italy to film commercials. Here she meets Prince Cesare Della Romita, a widower with six children. He proposes marriage, but she rejects him. Diana returns once more to London and Robert, but this time she realizes that their affair is truly over. In a search for security, she agrees to marry the prince, but he finds little time for her in his busy schedule. Bored and lonely, she returns to Robert for the last time. They spend a night together and make love, but in the morning Robert sends Diana back to Italy. Diana weeps as she contemplates her affluent but empty life.
