In the smoke of war in Songhu in 1937, two fates collided in the iron cage:
Shen Xiu, an economics professor at Hujiang University, was imprisoned for saving a Jewish student. Bai Mansheng, the top singer of Paramount, took the initiative to join the tiger's den for revenge. When Shen Xiu found the silver lock around the other person's neck that matched her own in prison, the truth about the bloodline of the pearl in troubled times was suddenly revealed - they were actually sisters who had been separated since childhood.
The cheongsam is a blade and the lily is a talisman. The elder sister used her economics skills to pierce the financial secret war and forged Japanese military bills in Hong Kong to paralyze the South China economy; the younger sister used her singing voice to convey top-secret information and hid the microfilm in Zhou Xuan's master copy of "Shanghai at Night". In the wedding trap of Chen Xiaoyun, the leader of Agent No. 76, Bai Mansheng's wedding dress was wrapped with explosives in its lace, and Shen Xiu's torch lit up the magic cave archives.
At Huishan Pier in 1945, Shen Xiu clutched half of the burnt cheongsam snatched from the scene of the fire, and could not hear her sister's laughter amidst the cheers of the Japanese surrender. Four years later, when Shanghai was liberated, she buried the silver lock on which her academic medal was cast, and the radio current suddenly transmitted her sister's unfinished pipa playing - it was "Songstress from the End of the World" they performed together in the attic on a rainy night in 1943, and now it has become a requiem that transcends life and death...
