In 1992, Pingba Town on the Lingnan border became a place outside the law: drugs were openly sold, guns were everywhere, unlicensed military vehicles were rampant, evil forces colluded with officials, and violent resistance to the law became the norm. Lin Weiguo, a police officer at Lancheng Detention Center, suffered from the pain of dereliction of duty due to the mysterious escape of death row inmate Ma Xianghai three days before his execution. He volunteered to go to Fangpingba, codenamed "Dongguai", to lurk to track down fugitives and the local black industry chain.
He stepped into this chaotic land and saw that the police station was like a battlefield, the deputy mayor blatantly protected the gangsters, and the undercover investigators had their hamstrings brutally broken. Under the leadership of director Zhao Guangming, Lin Weiguo gradually went deep into the undercover from the fringe, and joined forces with informants to collect evidence. After going through casino raids, armed confrontations, and martyrs' sacrifices, he finally waited for Lei Lei to close the net.
The superiors set up a Hongmen Banquet to remove the protective umbrella headed by deputy mayor Li Hongbin in one fell swoop; three thousand armed police surrounded him and killed the stubborn drug lord, ending Ma Xianghai's criminal life with his own hands. In the face of tragic sacrifices and heavy resistance, a special operation to soothe people's hearts and eliminate evil through law completely eradicated the cancer and restored peace to the border. This is a just battle fought with passion and faith in a lawless place.
