Back to the Future Part III. 1990. Can't remember I saw Part II. I'm think it was on VHS because I literally have no recollection of seeing it in the theater, but I distinctively remember seeing the trailer for Part III at the end of Part II, before seeing part III. I think.
Stranded after a tragic plane crash, two strangers must forge a connection to survive the extreme elements of a remote snow covered mountain. When they realize help is not coming, they embark on a perilous journey across the wilderness.
