In the seventeenth year of the Republic of China, a floating body suddenly appeared on Jinmen Pier. The tattoo on the deceased's wrist vaguely matched the evidence of an unsolved case three years ago. Shen Yanwei, a top student in the forensic medicine department who returned from studying abroad, was temporarily transferred to assist the police station in investigating the case. The rumors in the old streets, the secrecy surrounding the mansion, and the deliberately erased traces at the crime scene all indicate that this was not an accident. She followed the clues and found that everyone around her seemed to be hiding secrets - her seemingly friendly police colleagues, the mysterious businessman who suddenly came to visit, and even her brother who had been with her since childhood, were all trying to hide something. When the pieces of the truth were gradually pieced together, she was shocked to realize that she was already trapped in a well-woven network, and the end of the network was closely connected to the old events of her family.
