Selected sequence
Rhinos are notorious for being disgruntled (when we see the by day) turn out to be different at night

Rhinos, normally disgruntled by day turn out to be affectionate by night – filmed with a starlight camera near a waterhole (21’33-23’50)
Deep under the Kalahari there is a vast cave system of sweet fresh water inaccessible to the outside world

The Dragon’s Breath Cave is large enough for three Jumbo Jets head to tail. One of the largest underground cave systems in the world.
