Dulce, last of the Alvarez family, lives with her mother in the Andes and is worshiped by Pancho, a half-caste. Gringo Burke, an American renegade, robs and kills her mother. Accusing Pancho of cowardice, Dulce vows to seek revenge. As a cafe dancer she meets Burke, and American derelict David Ross defends her against him. The eruption of Cotopaxi finishes off Burke and his gang, who have come to steal ore in the mines, and Dulce saves Ross from the burning lava.—AFI
