Jiangcheng is built along the river, with criss-crossing water and land transportation, and there are countless hidden crimes that need to be investigated under the undercurrent.
After a dangerous investigation mission three years ago, Xing Shen, who had lost his colleagues, was transferred away from the front line and devoted himself to the field of poison testing. He was cold-tempered and taciturn, and he always had an unforgettable knot in his heart.
Qi Ming, the seemingly casual and casual deputy captain of criminal investigation, is thoughtful and good at detecting subtleties. The two worked together on multiple serial murder cases and worked together to clear away the layers of fog.
A mysterious poisoning case occurs in a college dormitory. Multiple suspects have their own selfish motives, and multiple incentives intertwine to lead to tragedy; a real estate businessman is killed, and his property involves gray funds; a corporate executive dies mysteriously in a hotel, and everyone around him hides his secrets; the missing insider leaves clues that point directly to the betrayer hidden in the system.
The clues of many cases are intertwined, all leading to traces of old cases left many years ago.
After key insiders came forward to testify, the police launched a unified investigation operation, and the identity of the traitor who had been hiding for many years was completely exposed.
Xing Shen was unfortunately injured during the arrest operation. At the critical moment, the two people finally confessed their hidden feelings to each other.
All the local gray industry chain strongholds have been investigated, and the leaders involved in the case have been arrested. However, the person behind the scenes who lives overseas is still missing, leaving many hidden dangers.
The city's surface has returned to calm, but the crisis lurking in the dark has not dissipated. Qi Ming and Xing Shen walk side by side, determined to continue to pursue the unsolved mystery.
Intention: Husband and wife join forces to break the prison of the abyss
