English actor Howard Wesley has fallen in love with 1930s Berlin and made it his home. He is approached by German intelligence with the offer of his biggest and most dangerous role ever. Who better than a native Englishman to facilitate Hitler’s plans to invade Britain?
But on arrival in Britain, Wesley’s plans start to go awry when he finds himself being pursued by MI5 agent Albert Stokes, himself recently plucked from obscurity as a bank clerk. The agent’s brief is to hunt down enemy spies and Fifth Columnists by posing as Hitler’s man in London.
As the danger of invasion grows by the day, can both men survive the suspicions surrounding them? When both become embroiled in the inexplicable bombing of a lemonade factory and the disappearance of an RAF Hurricane, events only grow more convoluted.
In a race against time, RAF Fighter Command strive to prevent the theft of a second fighter - and the net is closing in on the handler.
