The Phantom

The tribal leaders from unexplored jungles gather to meet with the Phantom, a supreme ruler who has taught the people to live together in harmony.

Professor Davidson searches for the missing part of a map that shows how to reach the lost city of Zoloz; the Phantom is trapped by another faction, headed by Dr. Bremmer, a secret agent head of a ring of foreign saboteurs.

The Phantom discovers that a number of outlaws plan to attack the Davidson expedition.

Fearing that Professor Davidson and his associates will learn of his plans, Dr. Bremer has his men capture the expedition.

In an effort to solve the theft of the ivory keys, the Phantom disguises himself, but also learns of a gunrunning plot.

The Phantom comes to the rescue when Byron and Mokue are ambushed on their way to Sitanna.

Dr Bremmer plans to dispose of Rusty and the Phantom. With Rusty as the trap, the Phantom unknowingly walks closer to his doom.

Dr. Bremmer fails to learn the hiding place of the stolen ivory keys from Singapore Smith, but when the Phantom finds them, Bremmer's men close in on him.

Dr. Bremer's men prepare an ambush at Martu Pass to stop Davidson from continuing his trek to Zoloz.

To get the Hastari tribe under his thumb, Dr. Bremmer conceives a fantastic idea.

To prevent Professor Davidson from learning about the seventh ivory key, Dr. Bremmer abducts Saka, chief of the Hastari tribe.

Still on the search for the seventh ivory key, the Davidson expedition enters Akida, where the Phantom tries to bargain with Tar Tar for the missing segment of the map of Zoloz.

Tar's men capture Diana and bring her to his castle in the mountains, but to gain her freedom the Phantom agrees to fight a gorilla.

Eager to reach Zoloz before any of the others, Byron sneaks away from the expedition in the dead of night.

The Phantom tries to rescue the Davidson expedition when Byron lures them into Bremer's trap in the catacombs of Zoloz.
