At the beginning of the episode, Toyomu talks about the National Fire Rescue Techniques Competition and mentions Yuki Nakamura's participation in the rope bridge crossing event. Her goal is to achieve first place. During a training session, Yamagami criticizes Usui for a technical mistake, while Igarashi encourages him and advises him to have more trust in his teammates Toake and Shun.

Meanwhile, Daigo encounters Matoi Sadaie from Shougadani Rescue. Daigo is surprised to meet Sergeant Matoi, whom he deeply respects. Matoi assists Daigo in an emergency and praises his skills. Daigo is impressed by Matoi's abilities and demeanor.

During training for the competition, Daigo and his team struggle to beat Shougadani Rescue's time. Matoi and Daigo exchange thoughts about their work and the challenge of always striving to save everyone.

Later, as the Tokyo Fire Department's internal selection process for the competition takes place at the Yumenoshima Training Center, various teams prepare, including Daigo's team, Fuwa Rescue. They focus on improving their rescue times. Teammate Usui even considers halting his strength training to reduce his weight and enhance his performance.

During this time, a high-rise fire is reported in Toyo Ward. Both the Fuwa and Shougadani rescue teams are dispatched to the scene. Upon arrival, they learn that the fire broke out in an internet café on the fourth floor, with several people trapped inside (referred to as the "252").

The episode transitions into intense rescue efforts. Daigo and his team face the difficult task of searching for survivors in the smoke-filled internet café. They speculate about the possible spread of the fire and the condition of those trapped. With limited time and resources, they split into groups to conduct a thorough search.

Daigo is determined to save everyone and recalls his conversation with Matoi about the significance and challenges of their mission.
