In the winter of 1925, Shen Yanzhi was rounded up by the military police at his father's funeral. He fled with the only token - the jade pendant that his father always held before his death. On the way, he was struck by lightning and awakened his supernatural powers. When he touched the jade pendant, he saw fragments of his father's memory of being poisoned by the Gu family doctor. He infiltrated into the dock under the alias "A Yan" and relied on his supernatural powers to find clues to the warehouse for smuggled arms from the old belongings of the porter of the Gu family. However, he was noticed by Gu Mingcheng and set a "pier fire" trap. Fortunately, Su Manqing rescued him.
The two formed an alliance, with Su Manqing providing media resources, while Shen Yanzhi used her powers to interpret the Gu family's account books and letters, and gradually pieced together the full story of the conspiracy: the Gu family used the Shen family's property as bait in exchange for support from the Japanese Chamber of Commerce, and the father's "evidence" was their smuggled arms list. During the process, Uncle Zhong appeared and told his father to hide the list in the secret room of the ancestral house. The three of them teamed up to sneak in, but were surrounded by Gu Mingcheng and Ichiro Tanaka. Uncle Zhong sacrificed his life to protect Shen Yanzhi and touched Shen Yanzhi's hand before he died, conveying the memory that "the list is behind the plaque in the ancestral hall."
In the end, Shen Yanzhi, with the help of Su Manqing, exposed the list through the concession newspaper, triggering public protests against Japanese power. Gu Mingcheng jumped over the wall and wanted to assassinate Shen Yanzhi, but during the fight, Shen Yanzhi touched his wrist, revealing his memory of forging "evidence of patricide". In the end, he was surrounded by angry people and was arrested together with Ichiro Tanaka. Shen Yanzhi stood in front of the ruins of the Shen family's ancestral home, buried the jade pendant in the soil, turned around and took Su Manqing towards the morning light - he knew that revenge is not the end, and preserving the integrity of the family is the best comfort for the deceased.
