Set in present-day London, a group of radical activists take over an energy company’s annual gala party, taking 300 hostages to expose the host’s corruption. Their righteous cause is hijacked by an extremist in their ranks who is willing to kill everyone in the building to send his anarchic message to the world. An ex-soldier turned window cleaner, played by Ridley, depends 50 stories outside the building to save those trapped inside, including her younger brother.
