Occupied Paris, 1943. Captain Erich von Adler is a traitor walking in plain sight—a decorated German intelligence officer funneling secrets to the French Resistance. His only contact is René, the pragmatic leader of a partisan cell, with whom he wages a clandestine war from the shadows.

But their dangerous game of cat-and-mouse is complicated by a powerful, unspoken connection that grows with every dead drop and coded message. When Erich's ruthless superior uncovers the scent of treason, their professional alliance is shattered. To survive, they must conspire to eliminate the hunter closing in on them, forcing them into a morally grey pact where the lines between duty and desire are irrevocably blurred. In a city of shadows, the most dangerous secret isn't about the war—it's about the heart.
