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