Kate (Thandie Newton) and Martin (Cillian Murphy) go to the isolated Blackholme Island off Scotland to escape London. They were there back in happier times in 2002. They are struggling with marital problems about a miscarriage. The power goes out. Martin is injured while trying to fix the generator. They call Doug for help on the radio but they get no help. Then they find a bloodied unconscious man. The man claims to be Private Jack Corman (Jamie Bell) and that there is a deadly worldwide airborne flu. The couple is suspicious of the erratic Jack.
The trio try their best to make an intense psychological thriller. The main problem is that the movie has one tone and one gear. It's steady and unrelenting. Jack doesn't change. He starts off scary and stays there. It may be more compelling to start off sane and build to crazy. It's intense but it feels like a manufactured thing. It's not realistic that Martin believes anything Jack says. Jack is basically acting like a paranoid mental case. There is nothing to prove his case other than his word. The movie needs to give the audience the permission to believe in Jack but it never does.
