Tales of a bipedal ape-like creature persist in the myth and legend of the Himalayas. But does the yeti really exist? Two enthusiasts are determined to find out.

Andrew Benfield and Richard Horsey begin their search in the north-east Indian state of Arunachal Pradesh.

Speaking to villagers and yak herders, they hear multiple accounts of yeti sightings. Will they find the evidence they need to prove the creature is real?
