Tales of the yeti—the Abominable Snowman of the Himalayas—have been recorded for centuries, and this huge, ape-like creature has tantalized explorers and mountaineers with its very rare sightings. On an expedition in Bhutan, Graham Hoyland filmed footprints of the mythical yeti (and might have even been pursued by one) in a part of the country that has never before been visited by Western explorers. As he delves into the fascinating history of this ancient legend, Hoyland also searches for the yeti's American cousin Bigfoot, the Loch Ness monster, and Africa's river monster Mokl-Mbmb. From the mystical pseudo-science of the Nazis to our current era of post-truth and fake news, Hoyland examines the age-old cultural phenomena that have fueled a belief in the existence of these creatures.
