The episode begins with the Fuwa Fire Station's response to a dangerous situation caused by Typhoon 12. The typhoon has grown large and powerful, posing a major threat to the greater Tokyo area. The firefighters, including Daigo and Shun, prepare for the upcoming challenges, demonstrating their dedication and readiness for action.

The main event of the episode is a rescue operation in the Ariwara district, where a steel tower is at risk of collapsing due to the strong winds. The Fuwa Rescue, Suginami Rescue, and Ariwara Command teams are dispatched to the scene. The urgency and danger of the situation are palpable as the teams rush to the site.

During the operation, Daigo discovers a basement room where people are trapped and in need of rescue. The room is rapidly filling with water, creating a perilous situation for those inside. Thanks to his quick thinking, Daigo devises a plan to lower the water level and facilitate the rescue.

The plan involves constructing a barrier around the door using partition walls and sealing the gaps with waterproof sheets. This allows the team to pump out the water using a pumper truck. However, the challenge intensifies as water continues to seep in, forcing the team to dive underwater to secure the panels.

The episode highlights the teamwork, ingenuity, and bravery of the firefighters as they battle against time and the elements to save lives. The intensity of the situation is underscored by the rising water level and the need for innovative solutions in the face of adversity.
