Plot

Tarzan and Jane are spending time by a river when they hear a scream. A local tribal girl has gone missing, and the tribesmen believe that it is the work of an evil spirit. Tarzan and Jane quickly realize that the girl has been kidnapped. The kidnappers are Lionians, a lost culture of men with a culture similar to that of ancient Egypt and who worship lions. The Lionians are kidnapping girls throughout the region and taking them to their city deep in the jungle. They have also brought a terrible disease that can kill within hours. Tarzan seeks the help of Dr. Campbell, who has a serum that can both cure the disease as well as vaccinate against it. After saving the local tribe, Dr. Campbell and Tarzan (with the help of Neil, a drunken big-game hunter) travel to the Lionian city.
