Botanist Frank Parrish leads an expedition to the Himalayas to seek out new flora, accompanied by hard boiled news photographer Peter Wells. When their lead guide, Subra, learns his wife has been kidnapped by a Yeti, Parrish disbelieves him, so the Sherpa commandeer the expedition at gunpoint and turn it into a search-and-rescue party. To Parrish's surprise, they discover a whole family of Yetis in a cave, and are able to subdue the male and carry it back to civilization, to ship to the USA for study.
