The film takes Chen Yongren's death as a dividing point, inserting sporadic fragments of Chen Yongren in the process of describing Liu Jianming's failure to "wash the ground".
In May 2002, Chen Yongren died six months before his death. Ah Qiang got into trouble at the massage parlor and called Chen Yongren to smash the shop and injure people. Ah Qiang was nagging because Chen Yongren was too heavy, like the Tang monk in "Journey to the West", and was flattened in the elevator by the "Supreme Treasure" Chen Yongren.
On June 14, 2002, Shen Chengshenliang, a brother of an outlaw businessman in the mainland (actually a public security officer), came to Han Chen to talk about business. Because of his distrust of Shen Cheng and Chen Yongren, Han Chen instructed Chen Yongren to beat Shen Liang. The two were arrested by Yang Jinrong, the chief inspector who was investigating Shen Cheng.
At this time, Huang Zhicheng's daughter was full moon, and Liu Jianming's wife was pregnant.
Chen Yongren, who escaped the disaster, went to see a psychologist (Li Xin'er) after Huang Zhicheng's operation so that he would not be arrested and imprisoned by the Department of Justice. Chen Yongren received a psychiatrist treatment cycle of 6 months, Chen Yongren was worried about being hypnotized by the doctor, at first he did not cooperate, and then slept with the doctor as soon as he came to the doctor, and exchanged feelings with the doctor.
During this period, Silly Qiang and Chen Yongren negotiated with Shen Cheng about the arms business. Chen Yongren then follows Han Chen to the library and discovers that he and Yang Jinrong have met (at this time Chen Yongren does not know Yang Jinrong).
On the day of delivery, Chen Yongren was betrayed by Han Chen, the arms were dropped, Chen Yongren, Yang Jinrong, and Shen Cheng did not fight and did not know each other, it turned out that all three were policemen. After the transaction failed, Shen Cheng returned to the mainland, and Chen Yongren went back to restore his vision.
In November 2002, Chen Yongren took out drugs hidden in a video store and sold Liu Jianming a gall machine (the two did not know each other at this time).
After that, the plot of the first part, Han Chen's criminal group was cracked, and Chen Yongren was killed in the line of duty.
In December 2002, 10 days after Chen Yongren's death, Yang Jinrong and Shen Cheng came together to pay homage to Chen Yongren.
Liu Jianming worked in the Ministry of Public Affairs during the investigation.
In October 2003, Liu Jianming deceived everyone by virtue of his ability to "write a report" with his own hands, successfully exonerated himself, and was reinstated as an official.
One day in September 2003, Yang Jinrong of the Security Division used drugs to coerce the owner of the nightclub into planting two arms dealers (the drugs were supposed to be Yang Jinrong, whom Chen Yongren took out of the video store and handed them to Han Chen, and then Han Chen gave them).
Later, in the Security Division, Sheriff Chen Jun committed suicide in front of Yang Jinrong, chen jun was later confirmed to be Han Chen's person, and Yang Jinrong was "given a month's leave".
In October, Liu Jianming went to the Ministry of Internal Affairs to continue to investigate the undercover, because Chen Jun committed suicide, so Liu Jianming suspected that Yang Jinrong was also undercover. Later, a photo of Yang Jinrong and Shen Cheng was found in the evidence room. Combined with the statement of another slain undercover b (Lin Guoping), there are 5 undercover agents, and Yang Jinrong should be the last undercover who has not appeared. As long as Yang Jinrong is killed, his secret will not be exposed.
In November, Li Xin'er returned to Hong Kong to visit Chen Yongren in front of the grave, so sad that she could not help herself, and asked Liu Jianming to talk to her. On the same day, Liu Jianming stole his computer, wanted to check Chen Yongren's information, and began to spy on Yang Jinrong.
At the same time, Shen Cheng came to Hong Kong again to cooperate with Yang Jinrong in investigating Liu Jianming.
Yang Jinrong took out a box of audio tapes from the safe and went out to put it into the mailbox, Liu Jianming could not take it out and burned the mailbox, this scene was seen by Shen Cheng.
A few days later, Li Xin'er called Liu Jianming and said that she had received an audio tape from Chen Yongren. Liu Jianming then arrives, and in a car accident on the way to the police station carrying Li Xin'er, and hallucinates in the hospital, Liu Jianming gradually thinks of himself as Chen Yongren. Li Xin'er discovers Liu Jianming's abnormality, hypnotizes him and discovers his secret. After Liu Jianming stunned Li Xin'er, he infiltrated Yang Jinrong's office to retrieve the audio tape from his safe, planning to arrest Yang Jinrong.
Inside the police station, everyone confronted each other, Liu Jianming regarded himself as Chen Yongren, Yang Jinrong as Liu Jianming, and took the evidence of Liu Jianming's undercover to arrest Yang Jinrong. Liu Jianming, who had endured pressure for more than half a year, collapsed, killed Yang Jinrong, and attempted suicide, paralyzed for life.
Yang Jinrong is actually han chen's undercover, but he is a "double-sided spy", he is smarter than Liu Jianming, more intelligent than Chen Jun, Lin Guoping, and his memory is good, he remembers Liu Jianming who entered the police academy together, he remembers Chen Yongren of the police academy, so he has the highest position. His identity should also be known to his superiors, and they used this advantage to continue to dig up Liu Jianming, the deepest hidden undercover.
