Due to the needs of the mission, three young martial arts students - Xin Xiaojing, who is good at persistent fighting, Cheng Tang, who is smart, and Bai Daqing, who loves parkour, won the favor of Captain Zhang Lan with their respective expertise and applied to join the police force. The three sneaked into the criminals' lair and carried out secret arrests. After the first shot, the SWAT team formed a rapid response team "Bow Hunting" team with martial arts students as the core force, and under the guidance of psychologist Chen Cheng, tailored a hell-style training trilogy for the newcomers to get rid of their "wild fox Zen" habits and cultivate the discipline and sense of honor of the police force. The enemy counterattacked several times, and Xin Xiaojing and other team members experienced baptisms of blood and tears again and again, faded from youth to maturity, withstood various tests from the outside and the heart, and became excellent SWAT members, always sticking to the front line of protecting the lives and property of the people.
