Liam Neeson stars in this action flick which is pretty much 'Taken' but on a plane. He plays an air marshal on a transatlantic flight who receives mysterious messages in which an anonymous terrorist threatens to kill one passenger every 20 minutes unless a ransom is paid. He searches the plane for the criminals responsible, but his investigation is threatened when he is framed as being the mastermind behind the plot. And sure it's non-stop.
