Shen Xiyin, a cold elite female surgeon, reunited in the emergency department with her ex-boyfriend Jiang Chi, who had been separated for five years and is now the captain of the special service fire rescue station. The two were at odds with each other due to past misunderstandings and personality differences, but were forced to fight side by side due to sudden disaster rescues (car accidents, floods, earthquakes). In the baptism of blood and fire, Shen Xiyin saw the passion and pain under Jiang Chi's cynical appearance, and Jiang Chi also fell in love with her again who was calm and decisive on the operating table. The two healed each other's family trauma and professional PTSD (post-traumatic stress disorder), and finally found a balance between national justice and personal emotions, becoming each other's strongest support.
