Tatsuya Hasebe, a student aiming to become a pararescue jumper, confesses that he made a false accusation about the power harassment allegations against his instructor, Seiji Usami, which has developed into a major issue. Usami is released from self-restraint and can return to training, and the morale of the students rises. However, Hasebe has begun to think about something during this series of turmoil...!? Meanwhile, an emergency call comes in saying that Ren Nishina (Gaku Hamada), who was dispatched to an area affected by a large-scale disaster caused by a linear precipitation band, has been caught in a slope collapse and is missing. While the instructors are shocked, Usami, who was fond of Nishina and was the first student he was in charge of after becoming an instructor, strongly believes in his survival and acts bravely. Nishina's wife, Mei , who received a call from the training unit commander, Horikoshi Shoichi, also continues to wait prayerfully for her husband to return.
