## Plot

The ICAC has been investigating a serious illegal domestic sales bribery case for many years. However, the court orders a one-week postponement because the first defendant, Chen Chaoqun, the head of Li Da Trading Group, jumps bail and absconds. In addition, the only important witness and whistleblower, Xu Zhiyao, the former financial director of Li Da, is absent from court to testify. In order to smoothly retry the case in seven days, ICAC launches an operation. The captain in charge of the case, Chen Jingci, and the person who was responsible for finding witnesses, Jiang Xueer, were previously a loving couple working together in the ICAC. They have been separated for a long time and have to work together for the case. In the process of arresting Chen Chaoqun and searching for Xu Zhiyao, both of them accidentally discover a figure hiding behind them. The solution of one mystery is the beginning of another mystery. The conspiracy behind it is far beyond everyone's imagination.
