Isabelle is a dentist that has been living with her boyfriend Pierre for ten years. When they decide to get married, Isabelle and her sister Coco are worried about the family curse that every first marriage ends in divorce.

They arrange a marriage for Isabelle with a student in Copenhagen so that she can immediately divorce to marry Pierre to live happily ever after.

But something goes wrong when on her flight Isabelle meets the inconvenient free-spirited tourism columnist Jean-Yves who is traveling to Kenya.
