Jungle Jim rescues a pilot after a crash landing, and the pilot, Ronald Cameron, passes himself off as a police inspector, assigned to the district to find Professor Dunham, a biochemistry researcher, who has disappeared. Cameron is actually the leader of a narcotics ring that has captured the professor and is forcing him to make a drug from a gland excretion of the Okongo (either midget zebras or painted-Shetland ponies), an animal sacred to the tribe that has been enslaved by the gang.
