Dr. Tracy and a hunter compete to find a lioness who is accused of attacking a villager, each agreeing that whoever finds her will do what they intend. A seven-year-old orphan, who hopes to stay at Wameru, is riding along with Tracy.
A young American from a wealthy family says he wants to learn survival skills and comes to Wameru and goes out with Mike and Bart to observe the lions. But he has a romanticized view of how nature should be and is upset when it doesn't conform to it. He also has other motives for his trip.
A new neighbor, a rancher from Wyoming, plans to buy more property around Wameru and fence it off, which will create a major problem for migrating animals. He also wants to use the area inside the fences for charging tourists to hunt animals, despite the objections of the Wameru staff.
A young man is banished from his tribe after he refuses to take on his father's role as the village storyteller. Ignoring Dr. Tracy's advice, he places himself in mortal danger in order to prove that he can be a great warrior.
While out with a husband-and-wife team of photographers, Jenny and Judy discover a cave with possibly significant archaeological artifacts. But the wife of the photography team, ambitious to get her husband recognized, hopes to insure that only they get credit for the discovery.
When Judy and Clarence go missing from the compound, Jenny fears the worst. To reassure her, Dr. Tracy tells Jenny about the adventures the chimp and the lion have been through before when they have taken off for extended periods.
