Liam Neesom plays a US Marshal aboard a trans-atlantic flight. The problem is that this flight is being terrorized by a killer that is murdering someone every 20 mins. The mania and panic that ensue is jarring, and the plot is gripping. Things are clearly not what they seem, although its hard to figure out what comes next. Everyone is a suspect. Everyone is suspicious. Although this is an action movie, it is also a thriller. If you are in the mood for a whodunit, this may be the right movie for you.
