British and Spanish monarchs once sent their best explorers in search of fabled South American gold. Hundreds of years later, evidence of their explorations lands into the hands of an anthropology Professor, but when the ancient coin is stolen and gold fever drives opportunists to kidnapping and murder, his daughter Oka is forced to guide her kidnappers through the jungle interior to the mythical city of gold. Faced with the same mortal race which once entwined Sir Walter Raleigh and Antonio de Berreo, Oka relies on her wits and her father's lectures to stay alive.
