Ghostkeeper

Ghostkeeper is a 1981 independent Canadian horror film directed by Jim Makichuk. The story centers on a trio of snowmobilers in the Canadian Rockies who become stranded at an abandoned hotel where an old woman seems to be hiding something.

The film opens with a title card reading In the Indian legends of North America, there exists a creature called Windigo... a ghost who lives on human flesh. The audience is then introduced to Jenny Riva Spier, Marty Murray Ord, and Chrissy Sheri McFadden, who are spending their New Years Eve on a snowmobiling trip in the Rocky Mountains. After talking with a man at a small ski shop, the three decide to go riding before dark, but end up caught in a blizzard. Looming before them is a seemingly abandoned hotel at the top of the snow trail, isolated from tourists and miles away from the skiing area.The three enter the building to escape the increasingly harsh conditions, and find that the heat is on there are, however, no working lights. As night falls, they start a fire in a fireplace in the lobby of the hotel, and tell stories and reminisce. Marty decides to go into the hotel kitchen where he finds an old woman Georgie Collins lurking. She is brash and apprehensive of their presence, and they learn that she lives in the hotel with two unseen sons she fails to tell them her name. ........
