On a family sheep farm in the interior of Australia, a brother and sister work the land while their reclusive brother, Wesley Antill, spends years toiling away in one of the sheds, writing his philosophy. Having forsaken the family business to travel through European cities in search of a foundation,Wesley returned home to spend his days holed up to write his magnum opus, trying to invent a new philosophy, a “theory of the emotions.” But after his untimely death, his papers are left untouched in his study, to be handled posthumously by his siblings. They call on Erica Hazlehurst, a philosopher, to travel from Sydney to appraise Wesley’s work to see if it is publishable. Accompanying her is her sexy and passionate friend, Sophie, a psychoanalyst who needs a distraction from a string of failed relationships. These two women, each with different views of the world and counter approaches to life, face a situation they have never experienced before, with surprising results. What begins as a spontaneous, brief sojourn will end up changing their lives.
