Mia and Ben, an Australian couple in their early thirties, have relinquished one dream and embraced another, selling their Sydney flat and purchasing an old yellow house in the picturesque village of Cordes-sur-Ciel in South-West France. They soon meet sophisticated neighbours Dominic and Susannah, a British couple in their sixties who welcome them warmly but whose own relationship is in crisis. Mia and Ben are immediately star-struck and impressed by their lavish hospitality. However, things with Dominic and Susannah are not what they first seem.
