1940. Great Britain stands alone in Europe against the growing stain of the rampant Nazi empire, its nervous inhabitants wondering what the future holds. But a handful of people on this beleaguered island know only too well what one possible future might hold. They have seen Warsaw burn, Poland crumble, France capitulate. Men like Jan Zumbach, Witold Urbanowicz, Miroslaw Feric and Tolo Lokuciewski, pilots of the Polish Air Force, who know that if the Luftwaffe isn’t stopped, then Poland, Holland and France were just Hitler’s hors d’oeuvres. So they are ready to fight, if they are given the planes. The problem is the British don’t trust ‘the bloody Poles’. And so the pilots, strangers in what seems a very strange land indeed, will over the course of a few months have to fight several wars at once – with the xenophobia of the authorities and the public, with the language, the unfamiliar Hurricane fighters, with the battle-hardened Luftwaffe. But once they are reluctantly made operational by the RAF, the Polish fighters show what they can do, out-gunning the enemy and out-scoring their allies. The once hostile British fete the Polish flyers as heroes – saviours, even. Now, though, the Poles have a fresh enemy – themselves, as nerves and fatigue take a terrible toll on men pushed to the limit by constant aerial warfare, fighting to save their own country above a foreign land. Not all will make it. Not all friendships will survive. And when it’s over, Jan Zumbach will contemplate a pyrrhic victory, as Poland is handed over to Stalin’s puppets.
