Zhou Jing, deputy chief physician of gynecology, was forced to occupy a seat and morally kidnapped by pregnant woman Lin Wei and her accomplice Gao Ming on a plane. She refused to tolerate it and was upgraded. Then Lin Wei suffered a sudden hemorrhage, and Zhou Jing discovered that this was a conspiracy hatched by her fiancé Chen Yang, who wanted to use high-altitude rescue to force her to take action and then blame her. Zhou Jing rescued her on the condition of video recording, immunity from liability, and donation and apology. On the way, she discovered that Lin Wei suffered from the rare coagulation disease PNH, and Chen Yangshi wanted to borrow a knife to kill someone.
