The tribes of Red Valley depart from what had been their homes for 8 decades after their ancestors survived an Apocalypse when their Airbus 388 crashed onto a remote mountain plateau in Ethiopia. Their pilgrimage faces many challenges during their trek through a hostile African environment that includes predatory animals, tropical diseases, as well as the feared and cannibalistic Lost Tribe. However, the greatest challenges lie within the tribes as they struggle to come to terms with fundamental differences between them that explode into violence and murder and threaten to sabotage the pilgrimage. They make a startling discovery to meet up with Beowulf the legendary hunter, who was the very first child born on KRAT eight decades ago. Is he friend or enemy? When the aMandawe attack the tribes, the legend of the Lost Tribe becomes a deadly reality. New leaders emerge while Karl the Navigator is accused by some tribes of leading them into the enemy's lair. After the Battle of Flat Mountain, the pilgrims eventually discover Mamelodi, the city of lost generations that is controlled by mysterious but beautiful Amazonian women.
