The story tells the story of fire station chief Song Yan (played by Yang Yang) and emergency doctor Xu Qin (played by Wang Churan) who separated due to family opposition in their youth. Ten years later, the two met again because of work. The plot unfolds alternately between the emotional pull of "reunion" and tense fire scenes and accident rescue fronts. In the process of jointly guarding the peace of the city, they finally solved the knot that had been in their hearts for many years and realized two-way travel and common growth.
