1937, Nanjing. Her codename is "Nightingale", and she is an agent rooted deep in the military; he, codenamed "Guzhou", is a lurker who wanders in the opponent's camp. An arranged partnership makes two parallel lines intertwined in the flames of war. She walked towards him step by step, only to find that her lover had another identity that could not be explained. At the same time, the British spy code-named "Shepherd" is weaving a dark web to carve up the East in the name of civilization. The last words of her comrades in arms and the sacrifice of her best friend pushed her to the cliff of faith. She finally chose the light she believed in and stood side by side with him to bring the enemies in the dark to justice. The Anti-Japanese War is victorious, but the future is uncertain. She left the old camp and headed towards the dawn of new China. In October 1949, she stood in that square and saw the light for all those who could not wait until dawn. Later, she became a diplomatic translator and he is still behind her. The long night is over, and the mountains and rivers have returned.
Intention: Persevere and fight in the darkness, and finally usher in the dawn of victory.
