Fire station chief Song Yan (played by Yang Yang) and emergency doctor Xu Qin (played by Wang Churan) reunited after ten years of separation. The two were forced to separate due to family opposition in their youth. When they met again, both of them had grown and changed a lot. Due to the nature of their work, Song Yan and Xu Qin gradually intersected. Song Yan led the firefighters of Shilitai to fight bravely to protect the lives and property of the people. After experiencing countless life and death tests of blood and fire, he still did not change his original intention. His persistence infected Xu Qin, and the knot that had troubled them for many years was gradually untied. The two overcame family resistance and finally came together again, encouraged each other, made progress together, and used their respective expertise to protect this beautiful city.
