The film tells of the beginnings of the Serengeti National Park in Tanzania. At the end of the 1950s, the Tanzanian National Park Administration wanted to fence in the protected area around the Ngorongoro Crater. Bernhard and Michael Grzimek were invited by the national park administration in 1957 to get a precise picture of the animal migrations and to provide the national park administration with the values ​​they needed for their project. Using a new counting method with two airplanes, the Grzimeks found out that the migration of the herds was different than assumed.

Mysterious Castles of Clay is a 1978 film about a termite colony; filmed in Kenya by film-makers Joan and Alan Root, and narrated by Orson Welles. (narration replaced by Derek Jacobi, in a later release titled "Castles of Clay")

Cheetah and Leopard... no animal can match the intensity of their power and grace. On the horizon, the next victim draws near, crouched in the grass, senses honed, an explosive rush, claws extend and then the final clamp of fangs in a jugular embrace. Discover what separates these predators from all others. The cheetah, the ultimate tactician, single minded in its abandon for the lightning-fast gazelle. And the leopard, an invincible opportunist lying in wait for the unwary. Both driven by pure instinct and the constant pressure to kill.

Looks at the baobab trees that grow in the dry bush country of Africa and shows the ecosystem created by them.
