Lion Gangland

The Serengeti is one of the most brutal environments on the planet. It's also home to the tough Vumbi lion pride. Using ground-breaking new tools (including a lion-proof peeping Tom robot), National Geographic explorers Michael "Nick" Nichols and Nathan Williamson embed with the lions to reveal a never-before-seen view into a world with razor thin margins between life and death.
