Synopsis：Song Yuanfeng is a criminal police captain in the most remote district of Haichen City. Born into a police family, his father is the deputy director of public security for the city, who firmly believes that his son should not receive any special treatment. One day, while on duty, Song Yuanfeng encounters a clash between drug gangs. He and his partner Wang Xun manage to apprehend a suspect involved in the case, but the suspect escapes before backup arrives. The internal conflict within the criminal gang sets the stage for the "Haichen Series" case. Due to his experience in this case, Song Yuanfeng is transferred to the city bureau's special task force. Under the pressure of being reprimanded by his father and mocked by his teammates for the escaped suspect, he embarks on a life-and-death pursuit of the gang involved. In the end, the Haichen drug cartel and its affiliates are wiped out. As Song Yuanfeng matures, he also comes to understand his father's good intentions.
