Set in the heart of government during a time of national crisis, this high-stakes Sky Original drama stars Robert Carlyle as Prime Minister Robert Sutherland, and Victoria Hamilton as his Chief of Staff, Anna Marshall.

Under the name COBRA, a team comprised of Britain’s leading experts, crisis contingency planners and the most senior politicians must assemble to help bring society back from the brink of collapse and deal with an unfolding national emergency after catastrophic events literally throw the nation into darkness.

Not only are they forced to contend with impossible political decisions and their ferociously pressured personal lives, but they must also be mindful of political opponents who will use any sign of weakness as the opportunity to strike.
