From award-winning filmmakers and National Geographic Explorers-in-Residence Dereck and Beverly Joubert, follow the journey of the lives of young male lions in the African bush and their potential to be king.

Join renowned wildlife filmmakers Dereck Joubert and Beverly Joubert as they capture the drama of Africa's largest free-roaming elephant herds on their timeless journey across the bush country of northern Botswana. Two years in the making, this remarkable documentary reveals extraordinary elephant behavior never before filmed. You'll see the rare adoption of an abandoned infant, the organized rescue of a calf in danger or drowning, and the haunting way bull elephants mourn the death of an aged companion. You'll also witness an encounter between a young elephant and adolescent lions that even surprised the filmmakers. Come with National Geographic on a journey you'll never forget - to a place where nature still rules and the elephant is king.

See firsthand the numerous changes that have led to dramatic decline of the lion population, and what needs to be done in order to ensure their survival. Live through some of the most extreme cat sequences ever captured on film. See a lion pride bring down a large buffalo, a blood feud erupt when scavenging hyenas move in on the kill and catch a glimpse of leopards who creep from the bushes to hunt and retreat into the trees before falling prey to larger killers. Beyond the blood and gore lies a stark reality: Big cats kill to live and live to kill.

It is a spectacle few have seen firsthand. Two foes trapped on an island in a remote part of Africa - and a battle to survive captured in high-definition over two years by award-winning filmmakers. Now, National Geographic takes viewers onto a unique battlefield in the Okavango Delta to witness the grueling fight for survival of highly specialized lions that prey almost exclusively on buffalo in Relentless Enemies.

Experience the wildlife of the Okavango Delta, an oasis and lush paradise in Southern Africa that connects a wide array of creatures. Lions chase elephants, who chase hippos, who chase crocodiles.
