In a picturesque village in England, Joan Stanley lives in contented retirement. Then suddenly her tranquil existence is shattered as she’s shockingly arrested by MI5...for Joan has been hiding an incredible past.
Cambridge University in the 1930s, and the young Joan, a demure physics student, falls intensely in love with a seductively attractive 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, leading Joan down a path that would confront her with an impossible choice in her future.
