When a solar eclipse happens, all of the animals flee and refuse to talk to Kimba. Boss Rhino informs Kimba of an old superstition, and it's coming true because Kimba's already betrayed someone he loves. Realizing he can't just forget about his sister, he goes off to search for her. Can Kimba save Leona before the prophecy comes true? Can he and his sister make up and work together again?
