Misplacement

When criminal policemen Jiang Guangming (played by Ma Yili) and Shi Luo (played by Gao Zhiting) were investigating a case, they stumbled upon the crime scene depicted in the novel by writer Gu Jiming (played by Tong Dawei) and the crime scene they were investigating bizarrely overlapped, fiction and reality are intertwined, everything is really just a coincidence? The appearance of the novel also provides a new direction for the tracing of the two, but at the same time, it also leads them to a deeper puzzle...... A case within a case, a mystery within a mystery, who is the murderer hidden behind the scenes?
