Ambitious model Diana Scott (Christie) uses her relationships to turn a low-rent career into a high-gear smorgasbord of jet-setting, love-making and the pursuit of hedonistic happiness.
But as she moves from one fiery tryst with a TV writer (Dirk Bogarde) to another with a suave playboy (Laurence Harvey) and yet another with a crown prince, she finds that happiness is the one thing that may elude her forever.
