In 1938 the Spanish Civil War has worn both armies and destroyed the mood of the people of both sides. The differences between national Republicans however are revealing: The fascist side has the unconditional support of arms and men facilitated by Hitler and Mussolini while the Republican army is ignored by a Europe more concerned of a possible World War than the fate of Spain. Thousands of young people between 17 and 18 rows are called by the republican army. These are the main characters, four young for whom the Battle of the Ebro will be the first direct contact with the war. This film tells the story of these young people forced to leave behind innocence and into whistling bullets.
