Faux documentary told in first-person narration, about an "adventuress" who sets sail to Guatemala with her father and two male crewmen, rescues them when their fresh-water supply is compromised, finds a treasure map, and attempts to steal a fabulous emerald from a ruined temple, much to the aggrevation of a worshipful native princess and her subjects.
