The series is adapted from the novel of the same name. Lin Luxiao (Huang Jingyu) has extraordinary firefighting skills and rich firefighting experience. He is the station chief of the Heping Road Special Service Station in Beixun City. By chance, he was selected to become an instructor for a reality show aimed at popularizing firefighting knowledge. In the show, Lin Luxiao met Nan Chu (Zhang Jingyi), a dancer he rescued from the fire many years ago. Nan Chu was full of affection for Lin Luxiao, but Lin Luxiao was reluctant to get close because he knew the dangers of his profession. Young and brave new generation firefighters such as Shao Yijiu (Li Mingjun) and Qin Shiquan (Chen Kang) have emerged, and Lou Mingye (Wang Ziqi), who brought back advanced equipment and technology from abroad, has also returned to the fire brigade. The three generations of firefighters, old, middle-aged and young, worked together in disaster rescue such as fire, earthquake, and air rescue, raising the level of fire safety in Beixun City to a higher level. Nan Chu and Lin Luxiao also gradually determined their feelings as they got to know each other better. Facing the most dangerous forest fire, Lin Luxiao and his teammates still chose to go against the fire.
