The Cold War has never been colder than in 2020's Brexit-era Britain. The United Kingdom faces the prospect of becoming dis-united and there is sporadic violent civil unrest. A series of cyber-attacks of growing severity affects all areas of daily life. Meanwhile, a hostile, foreign state mounts regular incursions into Britain's airspace and territorial waters. In the midst of the mounting chaos, a sinister entity calling himself WOTAK claims responsibility for much of this 'hybrid warfare' and seeks to hold the nation to ransom. A series of brutal murders, including that of the Foreign Secretary, raises the pressure on The Joint Intelligence Committee to establish who or what is WOTAK. With a little help from his friends, the Security Service's Harry Edwards seeks to track down and neutralise WOTAK. However, he has no idea of the enormous personal cost this complicated operation will involve.
