Episode 3

The climax to the BBC Natural History Unit's wildlife adventure series searching for tigers in the Himalayas.

Following extraordinary rumours of tigers living in the mountains of Bhutan, the expedition shifts to high altitude. Cameraman Gordon Buchanan captures remarkable footage of a snow leopard cub from over 5,000 metres in the air.

Along the Tibetan border, explorer Steve Backshall treks to the mystical Tiger Mountain. Helped by a remote tribe, he has a very close encounter with the world's most elusive predator.

The plight of the endangered tiger brings biologist Dr George McGavin to tears, and the team present their findings to the Bhutanese Prime Minister. As the expedition culminates, Gordon makes the discovery of a lifetime.
