Secretly married for three years, tower air traffic controller Song Qingyue and her captain husband Lu Chen's communication is left with only "takeoff" and "landing". On a thunderstorm night, she hears her husband flirting with the female co-pilot on the public frequency, yet she still guides them safely back to the ground. But Lu Chen not only erases her rescue credit, but also gives the plateau contingency plan she wrote overnight to her lover for merit evaluation. Song Qingyue quietly leaves the divorce agreement, seals the evidence, and transfers to the Northwest. Lu Chen thinks she is just throwing a tantrum, until at the awards ceremony, twenty-three versions of operation records are projected onto the big screen at the same time—and the woman he demoted as "only knowing how to pass messages" has already grasped his life-and-death flight route in another control tower.
