In 2012, a 16-year-old patient Pei Chen and the attending physician Shen Nuo of Jiangtong Third Hospital, a mental hospital that made a splash across the country, mysteriously disappeared. Employees in the hospital suffered from nightmares and other serious illnesses one after another. The director resigned and the Third Hospital was sealed off.
In 2020, a murder case occurred in Jiangtong Third Hospital. The long-lost Jiangtong Third Hospital reappeared in the eyes of the world.
The murder cases are like a chain of iron chains, leading one to another, and each of them seems to be related to "Jiangtong Sanyuan".
Xiao Yun, captain of the Criminal Investigation Detachment of Jiangtong City Public Security Bureau, is very sensitive every time he hears "Jiangtong Sanyuan". He thinks that "Jiangtong Sanyuan" may have some secrets related to him.
On the long No. 9 Street, there are the weird "Palace of Rebirth", the noisy "Gold Hidden Club", the prosperous "Wanxiang Building", and the mysterious "Baicao Courtyard". They seem to have nothing to do with each other, but in fact they are inextricably intertwined. All the spearheads point to the "Jiangtong Sanyuan" and an organization called "Shixiao Society".
Where did Pei Chen and Shen Nuo go?
Why did Xiao Yun lose his memory?
What secrets are there on Street No. 9?
