The student Shin Sawai (Kano Maple Bead), who is determined to become a rescuer (commonly known as PJ/parasicrejumper), was shocked to learn that the rescuer who saved him when he was in danger in the snow mountain 12 years ago was instructor Usa Mishiji (Onno Saiyang), and was shocked...I'll ask Usami to tell me the details at that time.So Usami quietly tells the story of Sawai when he was admitted to the rescue helicopter UH-60J and found his father Yukizo Uesugi (played by Masato Wada).

The father died because of his willful actions, and Sawai, who had been regretting it all the time, and Usami, who kept asking and answering why he could not save Uesugi and whether his judgment was correct.Now that the students who are targeting instructors and rescuers, the two people who can finally talk about the day...!?

On the other hand, after talking to Sawai, she always felt that Usami's ex-wife Mako (Suzuki Kyoka), who looked a little strange, would rather tell her to convey her ideas well.So, Yuna (Ai Yoshikawa), who accidentally heard a conversation between her parents, put forward a proposal to other students...

At this time, Sayaka Fujiki (played by Akana Ishii), who quit his rescuer course, came to the Komaki Base...!?
