Mark Harper (Douglass Dumbrille), a Diamond mine owner hires pilot Steve Blake (Leif Erickson) and his pal Hoppy Owens (Frank Jenks) to find the village of natives who have hindered his mining operations. They crash land and the miner discovers that the natives are led by Meelah (Gale Sherwood) the white daughter of the people Harper killed to get the land.

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.
