Jiang Che, a former investigative reporter who was banned for reporting, transformed into a "civilian criminal investigation" anchor. He partnered with the technical genius Lin Xiaoman and made a living by live broadcasting the review of unsolved cases. His live broadcasts were always controversial - viewers scolded him for attracting attention, and criminal police captain Zhao Ye scolded him for interfering in the handling of the case. Until the serial murderer "Shadow" suddenly broke in and challenged him with details of the case to "dare you pursue him", the live broadcast became a public cat-and-mouse game.
From the mysterious text messages in the case of the missing working girl, to the gaps in surveillance in the case of a nursing home falling from a building, to the hidden clues in the case of the sudden death of an Internet celebrity, each case has a "shadow" hidden in it, gradually involving the old case of Jiang Che's father (former criminal police officer) "died in the line of duty". The millions of viewers in the live broadcast room have become a special "jury": nursing staff popularize common sense about drug use, students anonymously reveal campus scandals, retired forensic doctor Zhou Lao comments on autopsy details, and the collective wisdom occasionally breaks through the blind spots of the police, but it also almost destroys innocent people because of rumors.
When the truth points to the underground information network that controls the case, Jiang Che finally understands that the "Shadow" forced him to uncover the core of the network in an extreme way - it was the network that murdered his father. In the end, Jiang Che and Zhao Ye reached a tacit agreement to disclose all the evidence in a live broadcast on the entire network, but the price was the sacrifice of the "shadow" and the rectification of the live broadcast room. Before the screen went off, a new provocative message emerged. This live broadcast about truth and boundaries has never ended.
