Mystery hangs over the Rill Ski Resort in Colorado after a young skier is found dead by an animal. But no ordinary animal. The Town Sheriff (Clint Walker) and Naturalists believe it could be a Yeti - the creature that was seen for years in the Colorado Rockies and North Western America. After many other skiers are found dead, Tony RilI (Robert Logan) a good hunter sees a white creature disappearing into the woods. Worried he informs his Grandmother (Silyva Sydney), the ski resort supervlsor, but in order to keep her business she keeps the Resort open and says creatures are legends. After more attacks 2 ski champions (Bo Svenson and Yvette Minieux) go into pursuit to stop the beast.
