Spain, July 1938 The Republican army crosses the River Ebro in a last, forlorn attempt to change the course of the Spanish Civil war. The British Brigade is one of the first units to cross with orders to take the town of Corbera de Ebro and then push through the Sierra Caballs towards Gandesa. A young Brigadista, Martin Strachan, son of the famous war poet Lyndon Strachan, is amongst their number. He is wounded in a skirmish and left for dead in an abandoned house where a local girl called Julia finds him and decides to nurse him back to health. At the beginning of September the Nationalists begin to push the Republicans back towards the Ebro and the war returns once more to the Sierra Caballs with tragic consequences for Martin and Julia.
