1943, Nazi Berlin, high pressure suffocation.
Erica Hartmann, the cold-blooded ace cryptographer of the German Cryptozoology Agency, is actually Elizabeth Cole, a deep-sea undercover agent of British MI6. Her weapon is a sophisticated brain that deciphers the secrets of the Enigma machine and delivers intelligence to the Allies on the tip of the knife.
Soronia von Randolph, the apple of the Nazi general's eye, was a dazzling socialite in Berlin's upper class. Under the gorgeous mask, she is the fiery heart of the anti-Nazi organization "White Rose". She uses her identity as a cover to steal fatal information during the fight.
A banquet where dignitaries gather allows a cautious hunter to meet a dazzling target. Temptation, suspicion, and fatal attraction spread silently. When Erica intercepted the top-secret "Neptune Plan" intended by the Nazis to mislead the Allied forces to land in Normandy, but found that all transmission channels were blocked by the Gestapo, she was forced to send a dangerous distress signal to the only person who could break the situation - Solonya.
Identities are revealed in desperate circumstances: British spy and German resister. Suspicion turned into shock, and then into life-or-death trust. They work hand in hand in the dragnet woven by the Gestapo, using wisdom and courage to deliver information that changes the war situation. Cold codes and fiery ideals collide and blend in the smoke of gunpowder. The cooperation in the shadows breeds a passionate love that transcends positions and cannot be tolerated in the world.
However, on the eve of Berlin's liberation, the Nazi's butcher knife fell. Erica is deeply under suspicion, and Sorunya is wanted by the whole city for being betrayed by a traitor. Between the muzzle of the gun and the ruins, the shadow of death finally forced out the deepest confession in my heart. Can they protect each other in the darkest moment, survive the final madness, and usher in the dawn, under the sunshine of Berlin's liberation, holding hands together openly?
Intention: A forbidden love born among codes and lies, a song of hope written with life in the dark age.
