In a small town on the outskirts of Madrid, a funeral is taking place. Julio Carrion Gonzalez, a man of tremendous wealth and influence in Madrid, has come home to be buried. But as the family stand by the graveside, his son Alvaro notices the arrival of an attractive stranger—no one appears to know who she is, or why she is there. Alvaro’s questions deepen when the family inherits an enormous amount of money, a surprise even to them. In his father’s study Alvaro discovers an old folder with letters sent to his father in Russia between 1941 and 1943, faded photos of people he never met, and a locked grey metal box. The woman is Raquel Fernandez Perea, the daughter of Spaniards who fled during the Civil War. From the provincial heartlands of Spain to the battlefields of Russia, this is a mesmerizing journey through a war that tore families apart, pitting fathers against sons, brothers against brothers, and wives against husbands. Against such a past, where do faith and loyalty lie?
