In April 2018, Xicheng Flight Academy organized students to group into groups for solo flight training. Xu Tian, Gao Ye, and Chen Xi, who were good friends, were placed on the same general-purpose aircraft. Unexpectedly, an accident occurred during flight training. The crew performed improper operations during stall recovery, causing the aircraft to first enter a deep stall and then enter a spiral state, causing the aircraft to fail to make an emergency landing. Seriously injured Gao Ye and Chen Xi finally recovered their lives after rescue, but Xu Tian died after the rescue failed. After the accident, Gao Ye dropped out of the flight academy; Chen Xi went abroad for further studies. Xu Tian's girlfriend Liu Qing transferred to the air traffic control college and aspired to become an air traffic controller to protect the safety of aircraft flights.
Four years later. Liu Qing became the tower controller of Xicheng International Airport; Chen Xi, who returned from studying abroad, became a pilot as he wished, and Gao Ye, who was burdened with the past alone, changed from a "genius pilot" at the flight academy to a frustrated bird driver at the airport... This group of people who had never met again were reunited at Xicheng International Airport. During the investigations into the plane accident four years ago, Liu Qing gradually got closer to the truth and got acquainted with Takano. However, she did not know whether the person in front of her was the enemy who killed her boyfriend or the sweetheart she missed many years ago...
Concept: Planes are rising and landing, the airport is changing rapidly, and every instruction from the tower may change in the next second. So, you might as well move forward boldly, don't look back, seize the moment and live in the present.
