Princess Caroline was born in Monaco royal family. Her father is King Ranieri III, and her mother is Grace Kelly, a movie star married from Hollywood. Although the future kingship fell to her younger brother Albert, as the eldest daughter, she got the most love from her mother. In the eyes of her mother, she is "smart and eager to learn, full of yearning for life".

Caroline, 22, is slim and elegant. While studying at Sorbonne (the predecessor of Paris University), she fell in love with French culture and a French man, Philippe Younot, a brown-skinned banker, who smiled and showed his white teeth. The most eye-catching princess in Europe fell into the arms of a playboy. A year later, they promised in front of hundreds of relatives, friends and celebrities that they would love each other for life.

Two years and four months later, the promise was torn to pieces by lies and indifference. Caroline filed for divorce because she couldn't stand her husband's affair. It never rains but it pours. A sudden car accident claimed the life of mother Grace Kelly. After the funeral, Rainier III took Caroline's hand and said, "After your mother died, I hope you can bring me a miracle. You must inherit your mother's legacy because you have the same beauty and virtue. Seeing you solve my problem can bring me great satisfaction. "
