After a plane bringing home the workers of a remote oil rig crashes in the Alaskan wilderness, the survivors – a motley crew of "ex-cons, fugitives, drifters, assholes," to quote protagonist John Ottway (the always riveting Liam Neeson) – must fend off a pack of vicious wolves in this grisly, gruelling man-versus-nature thriller. Full of scary-intense sequences that practically make it feel like a monster movie, this adaptation of a short story by Ian Mackenzie Jeffers (who co-wrote the screenplay with director Joe Carnahan) is also a surprisingly introspective, occasionally downright emo film in which the characters spend much time reflecting upon their lives, struggling with faith and trying to come to terms with their seemingly impending death.
