Liam Neeson plays U.S. Air Marshal Bill Marks and on a flight to London his perseverance will be tested and sorely needed. Someone is sending him text messages and threatens to kill a passenger every twenty minutes if $150 million is not transferred to an account. The movie builds in the tension department as Marks continues to watch the passengers every time he sends or receives a message to learn who it is behind the terrorist activity. He elicits help in the form of a woman named Jen, played by Julianne Moore.
The journey to discover the person behind the threat twists and turns with some unexpected occurrences. The viewer also learns more about Marks, a man who loved his young daughter and lost her and now battles the bottle. The movie features several action sequences and builds the mystery of the unknown killer nicely. And Neeson plays a genuinely concerned official whose aim is to sincerely help the passengers survive. In a touching scene Marks, the same man who lost his daughter, is seen near the end attempting to save a young girl’s life that is about the age of his daughter when he lost her. Unfortunately, from a family perspective, the movie features strong language and violent moments so we are prevented from awarding it our Dove “Family-Approved” Seal.
