Grace Kelly was swept away when the handsome Prince Rainier, a man she barely knew, asked for her hand in marriage. After a series of relationships with married co-stars, she was exhausted by the show-business lifestyle. If she married Rainier, she would be more than just a movie star, she would be Her Serene RoyalHighness Princess Grace. Once in the palace, however, Grace found herself trapped in a fairy tale of her own making. Forced to make sacrifices that cut deeply into the core of who she was as a woman, she would then surrender her desires and ambitions for her spouse and her children. Grace and Rainier may have been royalty, but they were also husband and wife, and parents-and, as such, just as vulnerable to the conflicts that can contaminate any household. Drawing upon hundreds of exclusive interviews with family and friends, ONCEUPONATIME portrays its subjects with passion and sympathy, revealing Grace, Rainier,Caroline,Albert, and Stephanie in ways both startling and compelling.
