 Diamond mine owner Mark Harper (Douglass Dumbrille) hires pilot Steve Blake (Leif Erickson) and his pal Hoppy Owens (Frank Jenks)to search for a hidden jungle village from which the natives have made trouble for his mine operations. They crash near the village and discover that Meelah (Gale Sherwood), a white girl brought up by the natives after her parents had been killed for their property by Harper, is the head of the village. Returning to the mine, Harper, already suspicious of what they may have learned and jealous of the attention his wife, Connie Harper (Veda Ann Borg), is paying to Steve, has them jailed, while he leads an expedition against the village and Meelah.
