Deep in the Catalan region of Northern Spain, a cadre of ETA separatists plan to enrol Henri Argen, terrorist and gun-runner, to their cause. Meanwhile, taking things easy amidst the rolling Downs of the Sussex countryside, Jack Travers is enjoying life to the full. Then tragedy, awful in its intensity, strikes through his aparent tranquil existence. These two separate incidents combine to set Jack once again on the trail of his arch-enemy, Henri Argen. Together with Pierre Rahua, his French Secret Service companion, Jack uncovers a plot that, if successful, could blow the European Establishment off its very foundations.
