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