The human world is aflame with war. Nations clash with their neighbours, while the Kelvon Empire, bulwark of the human world, stands on the brink of civil war. The plans of the enemies of mankind to destroy human civilisation, to restore their own mastery of the world, are well on the way to success.

The people of Helberion have vowed to defeat those plans, though. Peace must be restored between the various peoples of mankind so that they can combine their efforts against their true enemy. Even while her country strives to avoid conquest and defeat at the hands of their traditional enemies the Carrowmen, therefore, Princess Ardria journeys to Carrow to meet with the enemy King in an almost hopeless attempt to persuade him of the truth. All her hopes rest on the assumption that he in an unwitting dupe of the true enemy, but lurking at the back of her mind is the fear that he may be all too aware of the truth, that he may have sold out humanity for the promise of personal power. If this is true, then all that awaits her at the end of her journey through fear and danger is imprisonment and the life of a hostage to be used against her father, King Leothan.

The Brigadier would help her if he could, but he and Malone, his former batman, are far away, each having their own missions to try and ensure the survival of human civilisation. Having completed his latest task, the Brigadier must race to join her, to assist and protect her, but will he reach her before she arrives at the palace of the enemy King? And will the Princess still have a country to be Princess of by the time she arrives there? Because even if Helberion manages to defeat the all conquering armies of Carrow there is another, even deadlier threat waiting in the wings against which there may be no defence...
