It is December 1941. World War II has become a truly global conflict with Japan attacking the American fleet in Pearl Harbour. The Luftwaffe are bombing English cities and the Nazis are about to launch their super battleship Tirpitz. With the tireless Winston Churchill as his boss, Colonel Julian Bonham-Johns from the Special Operations Executive is under pressure. As a ruthless foreign agent is making his way through the south west of England it becomes clear that a sinister Nazi plot is unfolding. In a bid to stay ahead of the enemy Bonham-Johns must mastermind a plan with the Allies and intercept the agent. It's a race against time to navigate tensions and egos while feeding lies and misinformation to the enemy. But all is not as it seems. Home Guard sergeant Bert Chenoweth hoped to live out his days in the beautiful Cornish fishing village of Porthcurno. He never reckoned on having to do battle again, but then he never reckoned on this kind of threat on his doorstep. Will he find it in himself to fight one last time for the things he holds dear? As the end game approaches, the enemies clash, head-to-head at Porthcurno Telegraph Station in a thrilling, violent and unexpected conclusion.
