Seattle Tower Air Traffic Controller Samantha and Captain Luke have been in love for six years. They thought they could go to City Hall to get their marriage certificate on their sixth anniversary, but at a dinner party, they heard Luke admit that he only wanted to forget about former instructor "White Moonlight" Sarah. During a crash crisis at an altitude of 10,000 meters, Luke instinctively protected Sarah, causing Samantha to be injured. Samantha, who had completely given up, decisively broke up and married Sterling Airlines President Davis, who had been saved by her and had a crush on her. In addition, Samantha's identity as the legendary captain of the "Spirit" was exposed and she returned to the blue sky; Sarah's true face of cross-border marriage fraud was exposed; Luke was ruined and regretted it. In the end, Samantha and Davis went through a test and held a romantic century wedding.
