ayou (played by wang xi) has been determined to become an excellent firefighter since childhood ddd。 as an adult, he and his friends ah xing (chan jiale) and ah ba (zheng jingji) applied for the fire school together. during this time, they met a yao (played by guan yonghe), ah bo (played by louis koo) and zi ji (played by deng zhaozun). after graduation, they were allocated to different fire departments. in addition to ah bo, they all sent to ah feng (played by li zixiong), and ah you's outstanding performance was even more appreciated by ah feng. ayou's mother suddenly became critically ill. what ayou unexpectedly expected was that he and feng were half-brothers. moreover, the two had great differences in work, and their relationship quickly cooled down. abo, who was sent to guard changzhou, had a relationship with his colleague a cui (played by liang zheng), but a cui has long been the girlfriend of his brother (played by zheng zicheng)... a group of fire elites, in addition to taking care of the lives and property of the masses, also have to deal with their grievances.
