As already stated in other reviews the film is about an Air Marshall with drink problems who is confronted with an unknown hijacker. He has to find him before things turn really bad. The film is okay but not any better than that. I am a big Neeson fan but I was disappointed with this film. The story-line was very predicable and it never seemed to build up any real tension for me. I don't want to give out any spoilers so won't go into detail but Neeson has done much better films. Some of the supporting actors were good, for example the co-pilot and stewardess. Though average it is worth watching.
