Modern actor Lin Zhiyi was involved in a car accident on the final day of filming the Republic of China spy drama "Miaoling Beacon". When he woke up, he was dressed as the Miaojiang voodoo girl in the script - Shen Qingyin, the eldest daughter of the Shen family. She thought she could control her destiny with the script in hand, but she found that the plot had already deviated: the engagement that appeared out of thin air, the temptation of the mysterious drugstore doctor, and the whisper of "you have read the script" from the Japanese military agent all told her that this time travel was not an accident.
Shen Qingyin used "Method Acting" to activate Gu, but found that all the truth pointed to a woman who had been missing for twenty years: her aunt Shen Yuehua. As the flames of the Anti-Japanese War spread across Miaoling, Shen Qingyin was forced to get involved in the vortex of the three-party espionage game between Gu Yunzheng (underground party), Dr. Zhou (military commander) and the Japanese "Ghost Chrysalis" organization. And when she used her own blood to cast a forbidden spell to save Gu Yunzheng, the Lianxin Gu bound their fates - her heartbeat would sting his wound, and her emotion would threaten his life.
More cruel truths followed: Shen Qingyin was not the eldest daughter of the Shen family, she was Shen Yuehua's biological daughter; the purpose of her time traveling was not to save, but to be a sacrifice designed to activate the "time and space Gu array". When Shen Yuehua left her the chance of survival before the army collapsed, she had to make the final choice between "returning to modern times" and "staying in the Republic of China."
How long does it take for an actor to act and become himself? When Gu Meng finally woke up, she realized that the greatest character was never the one written in the script.
