In a picturesque English village, Joan Stanley (Judi Dench), lives in contented retirement. Then, suddenly, her tranquil existence is shattered as she’s arrested by MI5.
We cut to Cambridge in the 1930s, and the young Joan (Sophie Cookson) falls in love with Russian saboteur, Leo. Through him, she begins to see that the world is on a knife-edge and perhaps must be saved from itself in the race to military supremacy. Post-war, Joan is confronted with the impossible: Would you betray your country and your loved ones, if it meant saving them? Inspired by an extraordinary true story.
