Set in present-day London, a group of radical activists take over an energy company’s annual event, taking 300 hostages in an attempt to expose the corruption of the hosts. Their just cause is hijacked by an extremist within their ranks, who is ready to kill everyone in the building to send his anarchic message to the world. It falls to a former soldier-turned-window cleaner, played by Daisy Ridley, to suspend herself 50 floors above the building to save those trapped inside, including her younger brother.
