Alexandra, a set designer, becomes a leading figure in New York's theatre world. Kay, who marries and moves to Scotland, designs a successful line of clothing. Jessica, an interior designer, makes her home in California, while Maria returns to her native Italy, where she continues to work in her family's textile business.

For each of them, the arrival of an invitation to Paris to celebrate Anya Sedgwick's eighty-fifth birthday stirs up complicated feelings: nostalgic memories are coloured by poignant regrets and the reluctance to revisit their own pasts mixes with curiosity about the other women. It is ultimately their desire to deal with unfinished business that convinces all of them to attend the party. During three eventful weeks in Paris, they visit their old haunts, rekindle ties, and awaken in each other the sense of wonder, adventure, and possibilities they had shared so long ago.
