A bickering young couple and their sexy female friend are snowmobiling in the (Canadian?) wilderness when they run across an old hotel where they are forced to seek shelter from a sudden winter storm. At first the hotel seems to deserted, but then they run into a strange old woman who claims to be the caretaker and alludes to a having couple of "kids" "around somewhere". As night falls one of the girls disappears and the remaining pair realizes all is not as it seems in the hotel. This movie can be easily written-off as a cheap, Canadian rip-off of "The Shining", but that's not entirely fair--it also rips-off other movies like "The Sentinel" pretty severely. And it tries, very ham-handedly, to mine the native Canadian legend of the wendigo (spelled "windigo here for some reason).
This movie has very little going for it. The plot is pretty dumb and derivative. The dialogue is generally clunky (except maybe for a funny scene where the sexy blonde friend tells a story about seducing a substitute teacher when she was in high school). The characters range from bland to genuinely dislikeable (especially the guy). The girls both look good in their snowsuits but have no nude scenes, which doesn't have to be a deal-breaker except that the movie has one of those famous non-nude bathtub scenes just to kind of rub in the actual dearth of real skin. The one good thing I can say about this movie is that it does have a pretty effective atmosphere. The gloomy, snowbound hotel is eerie and portentous, even if there is no real payoff to justify all the eerie portentiousness.
This movie was made in the early 80's when the American horror film industry was starting to go south (figuratively), and the Canadian film industry, encourage by friendly tax laws, started to go south (literally). This movie is a little more ambitious than most of the Canadian tax shelter projects in that it wasn't content to be just another "Halloween" slasher movie knock-off. It kind of reminded me of "Death Ship", so if you liked that. . . It's hard to find to find these days though and probably not worth looking too hard for.
