Thriller in which an ill-advised journey on a prototype plane lurches towards disaster when a virus devastates the plane's computer system and sends it out of control. Devain Industries are the owners of a computer programme designed by Tom Woodard (Casper Van Dien) and his wife, Samantha (Nicole Eggert), to enable planes to fly completely without human input, thus eliminating crashes caused by human error. Unfortunately, the billionaire owners of Devain, Charles (Patrick Muldoon) and Richard (Brad Dourif), insist on flying the prototype from Los Angeles to New York and won't listen to Tom's objections. To make matters worse, just before the VIP flight the reckless Charles uploads some software to the flight system that is riddled with viruses and quickly causes an infection to break out. Can Tom find a way to get the system back under control before the plane crashes or is shot out of the sky by the US Air Force as a threat to civilians?
