Wang Jixiang, Luo Xin, Zhang Xiaomei and other post-90s police academy after graduation were assigned to Yongcheng Xinqiao Police Station. Luo Xin was sentenced to 2 years in prison for the accidental death of a mentally handicapped girl when he went out to the police. The police station was in crisis, and the higher-level department sent deputy director Chen Xiaojing to take up the new director to deal with the mess. Wang Jixiang worked hard to correct the name of the post-90s police, and Mao recommended himself to be a community policeman, and finally won the understanding and trust of the masses after several ups and downs, and was affectionately called the "policeman next door" by the masses. After being released from prison, Luo Xin focused on public welfare undertakings and established the "Volunteer Service Association", which soon became the leading brand in the mass organizations and an important assisting force in the comprehensive management of social security at the Xinqiao Police Station. Zhang Xiaomei communicated with the masses in a novel way of live webcast, resolved contradictions, and won the love of the masses. After properly handling a series of incidents such as anti-crime and evil, arresting drug dealers, and public opinion monitoring, the Xinqiao Police Station regained its glory, and the post-90s police officers have made achievements in love and career.
