Three people, a father and his grown up kids is climbing something very high an brown, and the wire holding them is about to crack, so the father cuts his own rope and falls to the ground and dies, to save his children. Few years (about 5-7 i think) later the sibling meet again, because they’re going to climb this mountain that might be mt. everest, but I can’t remember, with a group of other people. I cannot remember the purpose, but I’m sure there was one. I don’t really rememer much from here, but of course there were a lot of snow, and they live in tents at night and there a doctor thing and one of them gets sick.

Later in the movie, someone want’s to kill one of them… maybe? At least someone is drinking yellow poison that looks like pee in the snow and he dies. I really can’t remember the end…

Yeah, that’s it…
