Bertie Gregory travels the world to show animals' lives like never before.

Bertie arrives in the Serengeti as the spectacular wildebeest migration kicks off. He’s here to film the fastest land animal on Earth: the cheetah. As he gets close to a mother caring for her tiny cubs and a young group of males executing phenomenal hunts as a team, he learns about the unexpected challenges the species endures.

With the expertise of entomologist and fellow National Geographic Explorer Dr. Samuel Ramsey, the series uses groundbreaking filming technology to reveal the extraordinary world of bees; and uncover their astonishing architecture and intelligence, unlocking their secrets and featuring never-before-filmed moments.
