In the hills of old Mexico the skirmishing that ravished the lives of its people continued intermittently for weeks. Lieut. Blanco’s sweetheart, the Senorita Armaje, having heard no word from him, goes to his camp, finds him, and determines to work for her lover’s side of the question. She dons the garb of a red cross nurse and enters the Federal lines and conveys to Blanco from time to time important information. She is finally discovered stealthily returning to camp and is placed under arrest. The spy, who has been sent out by the Federal Colonel Ferro, is badly wanted by the Insurgents, and is thrown in the hands of the Insurgent’s leader by the braveness of Armaje, who, as he is climbing over a cliff, chops the rope in two with rocks and throws him into their arms. Lieut. Blanco conceives the idea of dressing in Federal uniform and entering the Federal camp in person, using the spy to show him the way. After arriving in said camp, he discovers that his sweetheart has been placed under arrest on the serious charge of being a spy. He affects her escape. Col. Ferro, a ferocious Federal officer, after learning of her departure, makes dire threats to capture every Insurrecto in his territory and starts out to accomplish his end. He invades the Insurgents’ stronghold, and there, after terrific fighting, lasting several hours, he accomplishes his desires, and Lieut. Blanco and his sweetheart are made prisoners of war, the Colonel marching them onward to what end we know not.
