Top-notch air traffic controller Joan, in her past life, sacrificed herself to save a flight for her husband Gavin, only to be falsely accused by him and his lover Lynn, ending up tragically dead in prison. After being reborn on the day of the accident, she stored all the flight evidence in advance, used the rules to avoid traps, and publicly exposed their negligence and lies. Her former in-laws caused trouble over gambling debts, but ANN Airlines heir Lawrence stepped in to help. After the jerk and his mistress got out of prison, they deliberately staged a car accident to silence her, but rebellious flight trainee Tyrone risked his life to save Joan, and they developed feelings for each other. Joan then rekindled her dream of flying and became the chief trainer for special training.
