Doña Aguila, owner of a vast ranch and a valuable emerald mine in the Argentine, longs for her lost daughter, Conchita, and is victimized by her manager, Emilio Tovar, who is secretly stealing gems. Tovar goes to New Orleans to dispose of some emeralds, and persuading cabaret pianist Inez Remírez to impersonate the dead daughter, he schemes to divide her inheritance. Dan Prescott, a stranger, forces himself into their confidence and accompanies the couple on their return voyage. Doña Aguila's kindness causes Inez to repent and to refuse to carry out the plan; Tovar and his men attack the rancho to acquire an emerald necklace, and Inez rides for aid. Prescott, revealing himself to be an insurance agent, wins the heart of Inez, and Doña Aguila adopts her as her legal daughter.
