John Ottway (Liam Neeson) works as a shooter for a petroleum company. He works in Alaska and he shoots wolves who come to close to drill teams. The work is hard. The conditions worse. The snow is all around and the cold bites at you. Ottway doesn't have long on the job. He is about to board a plane and head out of here but he knows something is wrong. The other day he was spotting for a team and shot a Grey. He held his hand on the fur while it died and it was like to say we are brothers.
The plane ride is rough and the ice is all over the wing. The cabin light is low and most are sleeping when the planes begins to descend. In about 30 seconds they are all in the snow and most are dead. Ottway is thrown from the plane. He wakes up in the snow dazed and confused. He stumbles back to a part of the fuselage. He comes across Lewenden (James Badge Dale). He is dying and Ottway and a couple of men make him calm and talk him to the other side.
The following survived the crash Flannery (Joe Anderson), Diaz (Frank Grillo), Hernandez (Ben Bray), Hendrick (Dallas Roberts), and Burke (Nonso Anozie). If they stay with the remains of the plane they will die. The cold will take them one by one. What they should be worried about is the wolves. They are in their territory and they don't like it.
The first person to go is Hernandez killed while urinating. After that it's Flannery, who falls behind while the group is walking to some trees. Burke goes in the night because of the cold. One by one they are all dying. What they know is to survive they will have to fight the wolves. Not only do they have to worry about the wolves; they also must face the conditions. This is a story of survival but what's ironic is that Ottway wanted to commit suicide in the beginning of the movie. You see his wife had left him and he was tore up over it. Funny thing is when mother nature faces you off an instinct inside drives you to want to live and beat the odds. Director Joe Carnahan brings this story of life and death to the screen and makes you feel the need to survive. You get the idea that when times are tough it makes you do extraordinary things to want to live.
