While the students continue to challenge their limits while being pushed both physically and mentally, they finally start training in the pool. However, even Fujiki Sayaka (Ishii Anna), who has the ability to have competed in the National Athletic Meet in swimming in the past, continues to struggle. Pushed to her limit in training that simulates a harsh rescue site at sea, Sayaka is attacked by a fear of water. The more Sayaka struggles desperately to recover, the more she panics...? After completing the training, her classmate Sawai Jin (Kamio Fuju) offers her words of encouragement, but Sayaka can't hide her irritation, saying, "Don't look down on me just because I'm a woman."
Chief instructor Seiji Usami trains an elite team of rescue operatives to undergo daring missions in dangerous environments where others fear to go.
