Michael and Roberta Findlay’s version of the Yeti legend. A group of college students are led by their professor into the mountains in search of the Yeti. Each student is slowly killed of by what they believe to be the Yeti. However, it turns out that the professor and his friend, dressed up in a costume, both belong to a cult of cannibals and use the legend of the Yeti as a lure so that one survivor can go back and say the Yeti got them.

Horror film producer and director Michael Findlay was killed on May 16, 1977 in a gruesome helicopter accident on the roof of the (then) Pan Am Building in New York city. On his way to John F. Kennedy airport to connect with a Paris-bound flight, Findlay was planning to demonstrate his new 3-D camera to potential backers in France. Findlay and three other passengers were about to board the helicopter when its landing support collapsed. The helicopter fell onto one side and its spinning rotor blades decapitated Findlay and killed three other passengers. A woman on the street below was also killed when she was hit by a detached rotor blade from the helicopter.

For the film Funk (1976) he invented a new portable 3-D camera. When he was killed in the helicopter accident, he was on his way to Paris to meet potential financial backers for the camera and was holding a test model of his invention.
