Students who aim to conduct a year-long hell training with the rescuers (commonly known as PJ/parasecrejumper) belonging to the Aviation Rescue Corps.The sense of companionship finally began to sprout and faced various tests every day.

As the harsh sea comprehensive internship approached, the training of the three air cushion stations set up in the water began in the swimming pool while barely maintaining breathing.As a result, Hasebe Tatsuya (Watanabe Bito), who had difficulty breathing, lost consciousness.Seeing this scene, Tomoki Shirakawa (Maeda Rishitaro) was attacked by an inexplicable terrorist attack...

Baihe, who grew up in a maintenance facility and wanted to be a hero of maintenance facilities partners and aimed at rescuers, also ranked first when he passed the qualification and was relied on by other trainees.Shirakawa pretended to be calm and acted strongly. During the previous training, the drowning Fujiki Sayaka (Ishii Akai) and Hasebe's faces flashed back and trembled continuously.Looking at Shirakawa who was trying to get rid of fear and bury his head in reckless training, his friends began to feel incongruity, and the instructor Usa Mishiji (played by Ono Saiyang) who saw through Shirakawa's inner fragility earlier than anyone else...?

When his companions were worried about Baihe, they finally boarded the rescue helicopter UH-60J and actually conducted rescue training at sea.The door of the helicopter opened, and the students who finally suppressed their extreme tension and fear and began to prepare to land.Then, Shirakawa changed a lot... When the students were stunned, Usami made a decision.

On the other hand, one day, Usami's ex-wife Mako Nogi (played by Kyoka Suzuki) suddenly appeared in the instructor's room of the rescue education team...!?
