The episode opens with seven trainees who have just passed the extremely difficult selection exam arriving at Komaki Air Base, home to the Japan Air Self-Defense Force Aviation Rescue Wing. They are introduced as aspiring pararescue jumpers (PJs), elite rescuers trained to save lives in extreme conditions. The trainees gather nervously in a classroom where the training unit leader, Horikoshi, begins a lecture. Suddenly, the sound of a helicopter approaching interrupts the session. The trainees look up to see Chief Instructor Usami Seiji descending from a UH-60J rescue helicopter, immediately establishing his commanding presence.

Usami wastes no time and begins the training year with a harsh, unconventional approach. The trainees are subjected to intense physical and mental challenges designed to push their limits. Usami's methods are strict and passionate, emphasizing resilience and teamwork. Each trainee harbors personal motivations and secrets driving their determination to become project leaders within the unit.

One trainee, Sawai Jin, stands out due to his emotional burden. As a child, he was lost in the mountains with his father and was rescued by an air rescue team, but his father did not survive. Sawai carries deep guilt and a desire to become a rescuer capable of saving lives like his father's. This personal history fuels his seriousness and sometimes causes friction with Usami's unconventional training style.

During a particularly grueling training session, Sawai rebels against Usami's methods, struggling to reconcile his emotional pain with the demands of the program. Despite his closed-off demeanor, Sawai eventually opens up and confesses his feelings and past trauma to Usami. Usami's reaction is unexpected; rather than dismissing him, he responds in a way that challenges Sawai to confront his guilt and channel it into strength.

The episode closes with the trainees facing the reality of the year ahead--a "hellish" training regimen under Usami's guidance. The group is united by their shared goal but divided by their personal struggles, setting the stage for intense development and camaraderie as they strive to become elite pararescue jumpers.

This detailed progression covers the arrival, introduction to training, individual backstory focus on Sawai, his emotional conflict and confession, and the establishment of Usami's leadership style and the trainees' resolve.
