I think the movie you are thinking of was called Frozen... https://www.imdb.com/title/tt1323045/
Here’s a story of a real life version of this.... http://www.the13thfloor.tv/2017/01/03/the-real-life-frozen-woman-stranded-on-ski-lift-for-5-hours/
There was also a case I think about 10 years or so ago (I seem to recall it being at Whistler) where a young woman waited for about 3 or 4 hours and then ventured hand over hand to the nearest tower (which was quite some distance away) and then climbed down. That takes some guts even when faced with a life or death situation. I’d be worried about what would happen if someone in a search party started up the lift....
Yea that was the movie.
That woman you mentioned must have been pretty damn brave..
