In the fifth year of conflict, the master plan for the invasion of Hitler's Channel stronghold is the Allies' greatest secret. National security demands it doesn't fall into enemy hands. So when Colonel Hugh Kelso is pulled from the sea off German-occupied Jersey in April 1944, a major crisis erupts. Because Kelso is still alive and knows the exact details of the imminent invasion. To ensure the success of their offensive, the Allies launch a suicidal mission. To rescue the Colonel. Or silence him for ever.
