The Spanish Civil War was a war of attrition. In 1938 the War had already worn out both armies and the spirit of the whole population. The National army however had the support provided by Hitler and Mussolini whereas the Republican army was ignored by the rest of Europe as these countries were more worried about a possible world war. It is in these conditions that, in an effort to stop the National army from crossing the river Ebre, the Republic called to arms thousands of youths aged 17 and 18. The story of some of these youngsters is narrated by Parrado with fresh enthusiasm and passion, all the while staying true to the facts.
