All six episodes from the first season of the British political drama starring Robert Carlyle and Victoria Hamilton. After a solar flare hits Earth and a nationwide power surge leaves the country without electricity, chaos descends when those worst affected by the crisis are the most vulnerable. When anarchists take to the streets to fight back against the government's lack of control, it is up to Prime Minister Robert Sutherland (Carlyle) and the members of COBRA to take decisive action and restore the country to normality before it's too late.
