A Small Country is the story of the Evans family, farmers in Carmarthenshire. In the summer of 1914 son Tom returns from Oxford to find the family falling apart. His handsome father has gone to live with schoolmistress Miriam Lewis, who is to have his child. His mother, broken-hearted, lies ill in bed, while his beautiful sister Catrin longs to leave for London and art college. Soon Tom's university friend Edward will arrive to holiday with them, half-aware of his attraction to Catrin, but already engaged to Rose, a supporter of the Suffragettes. And Tom himself is in debt and disillusioned with his proposed legal career. He would like to manage Hendre Ddu, the family farm, but finds his family troubles and the approach of war set him on a very different course.
