Veteran filmmaker Simon King takes on the role of mother to two cheetah cubs, Toki and Sambu, orphaned when their mother was killed by a lion. It's a two-year emotional rollercoaster, from terrifying stand-offs with rhinos and leopards to some of the most intimate moments of cheetah life ever captured on film. The cubs evolve into sleek hunters, spending more and more time on their own. But for Simon, it's a nervous time. Can they survive the dangers of the bush?
