Richard, a pharmaceutical salesman, is assigned to introduce antidepressants into Africa. Rachel finds herself Africa-bound too, in search of a little brother or sister for her daughter. For both Richard and Rachel, the excursions will lead them into their own private heart of darkness. When foreign families converge on Provence for a better life, it seems as if sunshine, drinking & partying will create an idyllic community of like-minded sorts. But compelled to venture far from this Eden to Africa, two of the couples' lives are changed irrevocably when each begins to doubt themselves, who they are & why they're there.
