"During World War 2, Churchill stumbles across a leak of vital information from the UK to the enemy and calls in Commander Jonathan Porritt to catch the mole. Porritt has no leads until Jane, a young British translator, unwittingly gets caught up with a German spy trying to flee the country.
Can Porritt use his Special Branch teams in Glasgow, Yorkshire, London and Belfast to rescue Jane and smash the undercover spy organisation before Churchill's invasion plans get leaked?"
Note: Sandra Maxwell has a major, though supporting, role in this adventure.
