After sisters Laure and Marie learn of their parents' plan to sell the family's summer retreat, L'Agapanthe, they devise a scheme for attracting a wealthy suitor who can afford to purchase the estate. For the sisters, it has become a necessary part of their character, their lifestyle, and their past. L'Agapanthe is the perfect venue to exercise proper etiquette and intellect, though not all its visitors are socially savvy - especially when it's a matter of understanding the relationship between old money and the nouveau riche. And so the comedy of manners begins.
