"Congo King" follows a celebration in the jungle where an old man reveals himself to be the true Congo King, exposing a woman who had claimed the identity and sought gold through his name; the real king punishes the impostor. "Jo-Jo" features a priestess of the jungle who battles falling meteors and mysterious forces, discovering that a gas used harmlessly by jungle doctors has been weaponized against her people in an attack on the village.

Marta MessaGeoffrey FordyceBak LeeRoger KerningMiss Perkins

In 1948, a cunning priestess named Marta Messa weaves an elaborate cult scheme around a legend—the Congo King himself—to bilk a wealthy believer out of his fortune, while her devoted servant Bak Lee silences anyone who threatens the deception. When Marta's plan brings her safari deep into the jungle to find the "living" JO-JO, she unwittingly sets in motion a collision between her hired impostor Roger Kerning and the real man himself, each unaware of the other's presence. What unfolds is a tangle of crossed loyalties, mistaken identities, and deadly consequences as JO-JO fights to clear his name and expose the truth behind the double double-cross.

The Cowboy and the Cayman!

Whether hunting by lasso during the dry season or tracking them by candlelight from a canoe at night, the cowboy's dangerous work is a constant battle against these prolific predators. This nonfiction account showcases the rugged skills and daily perils of life on one of South America's wildest ranches.

When fiery meteors rain down on the jungle, Jo-Jo faces an enemy unlike any before: Zalo, a towering woman who claims to rule through otherworldly powers, and her ring of deadly vapor that leaves even the mighty Congo King helpless. As the village falls under her grip and a mysterious white man named Benson pulls the strings from the shadows, Jo-Jo must uncover the true nature of Zalo's abilities before her "last raid" destroys everything—and everyone—he holds dear.
