Dumped: Françoise has just been dumped by her husband for a much younger woman. In order to cheer her up, and to celebrate her 60th birthday, sisters Rose and Alice decide to take their mother to a resort on the tropical island of Reunion so they can relax, work on their tans, and have too many margaritas. But when Rose pays a one-night stand, Thierry, to show her mother a good time, their holiday plans start to unravel.
