Join Frans Lanting and Chris Eckstrom on Saturday, January 26 at 3 p.m. and 7 p.m. for a remarkable journey to uncover the secret life of the cheetah--the fastest animal in the world, and the most vulnerable of all the big cats. In this year's show, Frans and Chris travel from the fabled Serengeti Plains of East Africa to the remote deserts of central Iran, where Frans gained exclusive access to document the last wild cheetahs left in Asia--cats so rare that few people know they exist.
