A documentary showing the struggle of the Spanish Republican government against a rebellion by ultra-right-wing forces led by Gen. Francisco Franco and backed by Nazi Germany and Fascist Italy.

This documentary tells of the struggles during the Spanish Civil War. It deals with the war at different levels: from the political level, at the ground military level focusing on battles in Madrid and the road from Madrid to Valencia, and at the support level. With the latter, a key project was building an irrigation system for an agricultural field near Fuentedueña so that food could be grown to feed the soldiers.—Huggo
