Lin Luxiao is the chief of the special duty station in Beixun City. He was chosen to be the instructor of a reality show that aims to popularize firefighting knowledge. During the program, Lin Luxiao met Nanchu, a dancer he saved from a fire many years ago. Nanchu is full of affection for Lin Luxiao, but Lin Luxiao is reluctant to approach her because he is aware of the dangers of his profession. A new generation of young and brave firefighters such as Shao Nixing and Qin Shiquan are emerging, and Lou Mingyei, who brought back advanced equipment and technology from abroad, returned to the fire department. All generations of firefighters worked together in fire, earthquake, air rescue and other disaster rescues, raising the level of fire safety in Beixun City to a new level. Nanchu and Lin Luxiao also gradually deepened their understanding in the determination of their own hearts.
