Chuan Dao quietly landed at Komatsu base, waiting for her is the flight monitor Qi Ying Mina (Yoshino Kimura). Rescuer Lennan (Dai Watanabe) reveals her distrust of Chuan Dao, while joking fighter pilot Yokosuga (Ken Kaneko) enthusiastically encourages her. In any case, the first female rescue helicopter pilot always stands out.
A fishing boat ran aground in the storm. Chuan Dao accepted her first assignment. Captain Waseda (JYUNICHI HARUTA) flies the helicopter, while Chuan Dao sits in the passenger seat and is responsible for navigation and communication. Rescuers Ishizaki (Juntai Nakamura) rescued the fishermen one by one, but when searching for the last victim, the helicopter's dye reached its limit and had to return. As the helicopter gradually moved away from the scene, Chuan Dao saw a man covered in oil climb onto the deck. She begged the captain to approach the fishing boat, but was severely rejected. Chuan Dao watched the figure being swallowed up by the waves. ...
The next day, depressed Chuan Dao sat alone in front of the warehouse. Lainan came to chat with her and told her about the death of her loved ones and the difficulty of rescue work. Soon after, Seonan was seriously injured in an accident during a mission. The driver Oda (Shunya Isaka) thinks it is his responsibility, and Bibi (Suzuki Sainai), who is in charge of maintenance, also blames himself. Encouraged by their partners, they cheered up again.
A month passed and Seonam returned from injury. At the same time, the news of Yokosuga and Bibi's engagement came out, and the team was filled with joyful atmosphere.
The alarm suddenly sounded and Komatsu rescue team went out. Yokosuga's plane disappeared from the radar, and the UH helicopter was put into search and rescue operation. Chuan Dao was ordered to fly the plane instead of the injured captain. The dye is about to reach its limit, but there is still no trace of Yokosuga. What choice will Chuan Dao make?
