Air marshall Bill Marks (Liam Neeson) is threatened on a transatlantic flight with text messages instructing him to arrange for $150 million to be transferred to an offshore account or someone on the flight will die. With everyone on board a suspect, Bill must be careful in who he trusts.
The film was quick to set up and put in place suspects that you watch carefully as the film pans out. The first thing to notice is the presentation of technology and the text messages that give it a strong visual style. Tension grips you right from the start and the claustrophobia of the plane is portrayed effectively.
