Avalanche (2001)

Policewoman Leah has never chased anyone as obsessively as Martin. She's convinced he's the madman who killed several women, including her sister. And now she's tracked him all the way to a secluded mountain cabin that he was apparently trying to escape to. Just as she aims her gun at him, the cabin door opens and out comes Jan, a physician who's come to spend a romantic weekend with his date. Before Jan can grasp what's going on, a shot rings out, triggering a giant avalanche. Once the masses of snow have roared past them, the four find themselves trapped in the cabin. Handcuffed by Leah, Martin claims that Jan is the killer, and that he was trying to prevent Jan from killing the young woman. Leah, who doesn't believe him, shovels her way out of the cabin with Jan. Together, they set out to find help, leaving the other two inside. Little by little, it begins to dawn on Leah that maybe she's locked up the wrong man.
