Jaume Collet-Serra’s new movie stays true to the title with “Non-Stop” suspense.

Bill Marks (Liam Neeson) is a guarded, alcoholic air marshal performing a routine trip aboard a transatlantic flight.

Soon after the flight takes off, Marks receives a string of text messages from an unknown passenger claiming someone will die every 20 minutes.

He is then given the option of transferring $150 million into an account in order to stop the murders.

Marks does his best to stay composed and keep the situation under control, which turns out to be quite a task thanks to defiant passengers, dead bodies and overall panic on the airplane.

Marks also has to convince his supervisor, the pilot and every other person onboard the airplane he is not the terrorist.

Although the plot might seem straightforward throughout the first half the movie, “Non-Stop” brings a few twists and adds a great deal to the tension.

Collet-Serra does a great job of keeping the viewers guessing as to who the murderer might be: the stereotypical Middle Eastern passenger, an irritable NYPD cop, a nosy woman interfering with Marks’s investigation or even Marks himself.

If you liked Neeson in “Taken” and “Taken 2,” then “Non-Stop” is an absolute must see.

Rest assured, Neeson pulls through in the film with his hoarse voice and determined attitude.

Collet-Serra puts you up close and personal with the fight scenes, yet does not overplay the almost cliché aspect of Neeson’s acting repertoire.

Instead, the movie keeps you on your toes with interesting dialogue and plot twists.

“Non-Stop” certainly brings up some current topics, such as national security, mistreatment of military personnel and corruption amongst people with power.

Filmgoers have the ability to look merely at the plot of the movie. However, it is suggested to analyze the movie beyond face value.

The ending of “Non-Stop” felt ambiguous.

Whether or not viewers feel cheated by the ending, “Non-Stop” will intrigue you and make your heart flutter a little.
