Cheetah are the most fragile cats physically and in numbers, now under 7,000 left in the world. Our story tells of Immani, a sleek female with 4 new cubs as they navigate the vast plains of the Mara ecosystem.

The film goes under the cover of darkness with thermal cameras, and when it comes to the hunting scenes, these are captured in ultra-high-speed.

Dereck and Beverly Joubert have made dozens of big cat films for National Geographic over nearly 40 years, but never one on cheetahs.
