A person has been arrested in the case of Ni San in Fujian. In the eleventh episode of the plot, the case changed. Gong decided to go to Thailand overnight. Under the instruction of the public security officers, Chen Pinzhu extended the call time with the British kidnapper as much as possible, giving Scotland Yard the opportunity to detect the suspect's specific location and arrest the kidnappers. Fuzhou also captured the suspect's accomplices. With the help of Thai police dispatched to Thailand, Ji Gongxu and Lin Lang, Chen Wei was captured and taken to China. This was the first transnational kidnapping case since the founding of the People's Republic of China and was finally solved.
