Jinghai City's frontline criminal policeman An Xin (Zhang Yi) was constantly attacked by the protective umbrella in the fight against the evil forces, and was unable to bring the criminals to justice. After the nationwide education and rectification work of the political and legal team was launched, Linjiang Province sent a guidance group to Jinghai, and jointly with the public security, procuratorial, judicial and judicial departments, eliminated the corrupt elements within the political and legal team, smashed the protective umbrella of the evil forces, and eradicated the powerful group that had been entrenched in Jinghai for many years.
