Alan King and Bert Hadley are representatives from an American Oil company who are in the African jungles looking to seek a concession from Chief Douanga for mining uranium on the land of Douanga's tribe. Kurgan, a trading post operator, is working on the behalf of an unnamed government seeking the uranium and employs Regas, an American, and Naganto, a witch doctor with Douanga's tribe who has been losing his influence thanks to the work of Carol Bryant, missionary's daughter who doubles as doctor for the tribe. Alan, Carol, and Bert battle to get their mining done while disrupting Kurgan's plots to kill them or drive them from the territory. The serial has a reputation of a formulaic Republic 50's entry with generic plot and abundant stock footage. This is not the case since there is a lot of new material especially when it comes to the cliffhangers (which have very good resolutions). Glenn is excellent as Naganto, and there is a lot of action here, but terrible gunfights since no one can hit the broad side of a barn. Moore and Coates seem to be going through the motions here, which gives the serial its drawback, as well as a climax in the quicksand which goes on too long. Rating, based on serials, 7.
