Scenario
In modern-day London, a group of radical activists take over an energy company’s annual gala and take 300 hostages to expose the corruption of the organizers. Their righteous cause is hijacked by an extremist in their midst, willing to murder everyone in the building to send his anarchic message to the world. An ex-soldier-turned-window washer, played by Ridley, must rescue those trapped 50 stories above the building, including her younger brother.
