In Yunhai City in 1995, a cash transport truck was speeding on the road but was hijacked by three gangsters. Old criminal policeman Liu Zhicheng was ordered to lead a team to hunt down the gangsters. He was seriously injured in order to rescue the hostages. Two gangsters slipped through the net. In the following four years, there was still no news, and the huge amount of money lost was also missing. One day four years later, the serial banknotes that were robbed appeared. A serial banknote involved Zhang Jinghua, a beautiful young woman who ran a barber shop, Zhao Dalei, the big boss of the nightclub, and others. Liu Zhicheng led the criminal police team to conduct in-depth investigations one by one through this small clue. Starting with Zhao Dalei, he followed the vines and finally met the old enemy who escaped four years ago - the gangster brothers Tieshan and Tielin. Liu Zhicheng faced the vicious gangsters and fought back bravely. This time, he would not let any gangsters escape. He led the team to start the ultimate action and start the final death showdown with the evil forces.
