Not a prequel to K-9, this is in fact about the second highest mountain in the Himalayas, reputed to be an even more dangerous climb than Mount Everest, and stuck with a Pakistani name so unpronounceable this film doesn't even bother to mention it.
Like Backdraft, but on a considerably less exciting level, this is essentially a re-run of all those 'dangerous profession' melodramas of the '30s and '40s, in which two he-man buddies brawl and booze between putting their lives on the line as test pilots/deep-sea divers/jungle explorers etc.
Here, wild and irresponsible Michael Biehn and happily married and irresponsible Matt Craven, whom you might just remember as the man in Jacob's Ladder who explains the plot, join up with a billionaire's K2 expedition and all the expected clichés of the genre are trotted out.The surly and untrustworthy native porters keep deserting the doggedly devoted white heroes, and the more disposable secondary characters get splatted by avalanches and freak falls.
The only surprise is that Biehn doesn't make any moves on the expedition's sole woman, perhaps because Patricia Charbonneau looks more butch in her climbing get-up than she did when she played a lesbian in Desert Hearts, and that nobody goes mad and wanders off into the snowy wastes in search of the abominable snowman.
