There is now a brief synopsis of the movie from here:
A contemporary double road movie set in Wales and Argentina. One of the film's narratives follows an old Patagonian lady (Cerys) and her neurotic neighbour's son (Alejandro) though Wales as they search for her mother's farm. The other story features the journey of a thirty-something Welsh couple (Rhys and Gwen) with fertility problems as they travel through Welsh Patagonia on a photographic trip. The language of the film is mainly Welsh and Spanish.
