January 1942: Former street-urchin, turned research assistant Samuel Irons accompanies his boss, David, on a trip to Africa in search of a fabled city. When a seemingly impossible storm hits their transports, Sam loses his mentor, and finds himself stranded, far from the adults on the expedition and deep in the Pridelands in the care of... King Simba and his pride. A few years have passed since the battle with Zira, and things have gotten to a state of normalcy when giant grey birds fall from the sky - something Sam calls "planes". While weary of this new creature: a human, Simba sympathizes with the orphan's plight deciding to teach him the Pride's ways along with his mate, Queen Nala - and grown daughter, Kiara. All is not what it seems, however. And when Simba and Nala make the decision of a formal adoption, the anncestors - the great kings of old - answer in ways both mysterious and worrisome. It will take the united front of both the expedition, and the Pridelanders, to right a past wrong, discover the shared history that brought them together, and most importantly, save the Pridelands from catastrophe.
