Old Mountain movie – Man is shot, falls into frozen river escapes, then is hunted down and kills all the men hunting him
After he climbs out of the frozen river, he dries his clothes by a fire, and then his attackeers find him, but he climbs a tree and kills one of them, and the movie goes like this untill every last one of them are killed
When you say ‘old’ do you mean old like 2006? If so, it sounds a lot like “Seraphim Falls”
