Chilean soldiers try to survive in the desert after they are attacked by Peruvian troops. The 17 survivors are held together by the Captain. The Lieutenant is a civilian attorney who clashes with the Captain as he pursues the valuable rights to nitrate deposits in the area. When the fighting was over, 25,000 soldiers from Chile, Peru and Bolivia had perished while trying to secure the coveted mineral rights for foreign companies.
