Documented in television documentaries for over 40 years by the BBC and other broadcasters around the world, the Marsh Pride is the most filmed pride of lions on Earth.

The Marsh Pride battle for survival in Kenya's famous Maasai Mara Reserve, which has become a magnet for tourists, many of them keen to see the pride for themselves. A tale of shifting loyalties, bloody takeovers and sheer resilience, the lions' story is told by those who filmed them, tried to protect them and lived alongside them, as well as some who ultimately wanted them dead.

Naturalists, guides, vets and conservationists in Kenya and back in the UK offer a unique perspective on the life of these lions. And the Maasai who live and graze their cattle next door to the pride speak about the struggles of living close to these dangerous predators. The Maasai themselves have been forced to give up their nomadic way of life and settle into a sedentary existence. So despite the long relationship of respect and knowledge between Maasai and lion, will it be possible to exist alongside these wild animals in the modern world?

Jonathan Scott and Simon King provide some narration.
