Academy Award winner Helen Mirren stars alongside Aaron Paul, Alan Rickman and Iain Glen in this timely thriller about a terrorist-targeting drone mission that becomes a flashpoint when a civilian girl enters the kill zone.

London-based military intelligence officer Colonel Katherine Powell (Helen Mirren) is remotely commanding a top secret drone operation to capture a group of dangerous terrorists at their safe-house in Nairobi, Kenya. The mission suddenly escalates from a capture to a kill operation, when Powell realizes that the terrorists are about to embark on a deadly suicide mission. American drone pilot Steve Watts (Aaron Paul) is poised to destroy the safe-house when a nine-year-old-girl enters the kill zone just outside the walls of the house. With unforeseen collateral damage now entering the equation, the impossible decision of when to strike gets passed up the kill chain of politicians and lawyers as the seconds tick down.
