After years of searching the Himalayas for the mythical yeti, Andrew and Richard were given a purported yeti hair in Bhutan. In this special bonus episode of the series, they send it to the US for DNA testing.

While they wait for the results, they hear stories of apparent yeti encounters from listeners.

When the DNA results finally come in, Richard is sanguine but Andrew is nervous. Will it be the evidence they’ve spent so long looking for? And what does it mean if it’s not?

In this documentary series, Andrew Benfield and Richard Horsey travel through India, Myanmar, Nepal and Bhutan in search of stories of yeti sightings and encounters. They hear from villagers, yak herders, sherpas and mountaineers, who give surprisingly consistent descriptions of a mysterious, large, hairy creature. This series takes us on a journey deep into Himalayan culture as the presenters grapple with their own inner demons to try to make sense of the yeti myth.
