The Shili Tai Fire and Rescue Station is in a festive scene. Suddenly the alarm rang, and firefighters were dispatched immediately. In the early morning, ER doctor Xu Qin had just returned from the emergency room after a major operation. A few firefighters covered in mud rushed in, begging her to treat his comrade who has a toothache. When she told the man to remove his mask, the man turned away and left the emergency room.

Song Yan was called to the Captain's Office. The team received complaints. Thanks to the persuasion from the staff officer, Song Yan got out of the siege. In the locker room, several colleagues were talking about Xu Qin, and it was rumored that she was the next person to be promoted. It was said that Xu Qin's family had an unusual background, and her colleagues were stunned. Xu Qin encountered a traffic accident on the way off from work, Xu Qin stopped immediately and prepared to enter the scene.

Song Yan came back from a mission and couldn't find the lighter, he ran to the garbage station to look for it. Song Yan told Suo Jun that the two had broken up due to family issues. Suo Jun comforted him. Xu Qin and Meng Yanchen came to the bar opened by Xiao Yixiao. After hearing that the fire department came to do a fire inspection, Xu Qin thought she could see Song Yan and ran out immediately. Seeing that Song Yan was not the one who came to check, Xu Qin felt depressed.

Xu Qin learned that Song Yan was on vacation. So she came to his aunt's house again, hoping to reconcile with him. Song Yan refused. In the fire station, Song Yan complained to Suo Jun about the poor performance of the recruits. Song Yan firmly believed that he and Suo Jun could turn Shili Tai into the best fire station in the country. Suo Jun dodged his eyes.

The driver who caused the accident surived, but the HIV-positive result of the blood test made everyone break out in a cold sweat. Not only were the doctors and nurses involved in the rescue at risk of infection, but the firefighters involved in the rescue that day were more likely to be infected. Xu Qin called the fire station, and all firefighters who participated in the rescue and were injured had to be checked. Xu Qin was worried and drew blood for Song Yan.
