Relentless Enemies: Lions and Buffalo (2006)

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.
