Once there, she settles in the beachfront hotel run by Monique, her own mother, who left the family eight years ago due to a serious marital crisis. Susanne's intention is to convince Monique to return to her home. But her mother is romantically involved with a handsome architect younger than her and to whom Susanne is immediately attracted.
