It is a TV series "The True Color of Interpol", which tells about the development and changes of the police force construction in China under the reform and opening-up environment, starting from the war between the police and criminal gangs in the 1990s.

Xiao Wen, Li Huai and Chang Chuang, graduates of Jiangzhou Police Academy, went to the Global Criminal Investigation Brigade respectively, accompanied by captain Pan Rong himself. As soon as they got started, they joined Pan Rong in the robbery. Xiaowen subdued the gangster with one shot and rescued Meili, the head of Jiangzhou Hotel Relations Department who was kidnapped.

Pan Rong was not satisfied with Xiao Wen's private photo, but the happy result made him respect his disciples all the more.

Mei Li's younger brother Mei Ying fights with street gangsters, and Xiao Wen pursues the perfect Mei Li by solving Mei Ying's problems. Mei Ying revealed that the back of the street rascal is the rogue Wang Wen. Two criminal gangs, Wang Wen and Zhou Shiwan, surrounded each other, while Xiao Wen and Chang Chuang tried to dissuade them. In order to save Xiao Wen, he was often stabbed.

Chang Chuang knew that Zhou Shiwan had cut him, but because he liked Zhou Shiwan's sister Zhou Lian, he didn't tell anyone about the murderer.

Zhou Shiwan was arrested, and he was confident to get out of prison and do something serious. The Criminal Investigation Brigade achieved remarkable results, so Pan Rong was promoted to deputy bureau, and Zhang was transferred to the police station as deputy director.

Xiao Wen's work of organizing the criminal investigation brigade also won Merry's favor. 1992, another batch of students graduated from Jiangzhou Police Academy, and Xiao Wen, Chang Chuang, who achieved excellent results, were assigned to the Criminal Police Team of the Public Security Bureau.

Pan Rong, the captain of the battalion, is a senior old criminal police officer with strong trial ability and strict rules for subordinates. As soon as the three men reported for duty, they were robbed in Jiangzhou Hotel. Under the command of captain Pan Rong, he rushed to the scene.

The kidnapped person is Guan Meili, the hostess of the hotel relations department; The kidnapper was strapped with a time bomb and a short knife was placed around Merry's neck. He was delirious and shouted that the manager Fang was unfair to her. He might as well be thicker.

When an emergency is imminent, there is still the danger of hotel bombing and casualties. Commandos have no shooting angle. Pan Rong, an old criminal policeman, can only outwit and persuade rationally, but it is useless.
