In northern Kenya, lions have begun to break into bomas, corrals made of densely woven vegetation, and take cattle. The people of the region are poor and their cattle are their wealth and means of life. Why have the lions suddenly started doing this? Predator expert Dr. Lawrence Frank hopes to use National Geographic's CRITTERCAM, a portable camera and research device, to enter the territory of the elusive lions on the high plateau of northern Kenya. But this is the first terrestrial deployment for Crittercam. Can it take the beating of a 300 pound lion, and will it go where no one has ever gone?
