From a murder mystery to a high-stakes crisis 36,000 feet in the sky, "Non-Stop" has all the makings of an aeroplane-thriller classic. Air Marshall Bill Marks, an alcoholic, is fed up with his airline job, which he considers to be a boring desk assignment. While on a transatlantic flight to London, he begins receiving a chain of cryptic text messages from an unknown number ordering that he command the airline to wire $150 million into an offshore account. If he's unable to complete the task, someone will die every 20 minutes until the wheels touch down.
