Jungle Jim must protect rare pony-like animals whose glands produce a powerful narcotic. On the way, he fights a giant spider.

Jungle Jim aids the women of a tribe whose men have been enslaved by a narcotics gang to hunt down a sacred zebra-like animal, called the Okongo. This animal is the source of a powerful drug that the gang intends to exploit. Some of Jim's obstacles include a leopard and a giant desert spider.—Geoff

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.—Les Adams <longhorn1939@suddenlink.net>
