Peter has a sister, she's a mountain climber, so is he; Peter's sister has got herself and her team stuck somewhere up K2, Peter's going to rescue her, against the odds... obviously. There's some Hollywood angst, a nasty man, a couple of good men, some sibling bonding, one or two good action sequences, all bulked out with a lot of tedious drama and accompanied by a script that would insult the side of a cereal packet.
