“This is the 119 Fire Center.Is it a fire or emergency rescue?”

The person who answered the call was Yuki Kehara (Nana Kiyoshino) from the third team of the Yokohama City Fire Department Command Center.Next to her is the part-time instructor Mutsuo (Seto Yasuji), who is instructing her.Faced with the 119 call that was not an emergency, Mutsuo had a stern attitude, and the team leader Kazuyo Takachiho (Yuri Nakamura) could only smile helplessly.

During the break, colleagues - Go Shinnosuke (Ichinose Sa) and Minawa Kensuke (Maehara Teru) - came to comfort Yuki, saying that although Mutsuo's guidance was strict, it would pass soon and asked her to be patient.However, Xue himself didn't seem to take it too seriously.At the same time, another colleague Niijima Sarada (Mikami Ai) did not participate in the discussion.

Takachiho calls Mutsuo to her desk and reminds him of his lack of tenderness towards Yuki's guidance.Mufu retorted that he did not think he was suitable for the guidance job from the beginning, complained that it was not a transfer period, and did not understand why Yuki was arranged here.Takachiho warned him that Yuki Kabara quit his job at the bank in order to become a dispatcher at the command center, so he must be trained carefully.In addition, Takachiho also revealed that Yuki has an extraordinary ability - she can remember any sound or audio she hears.

That night, when Dojima Shinichi (Sato Hiroshi) appeared in the command center, Yuki looked at him with admiration, and there was a specific reason behind this.At this moment, starting with the 119 call that Xue received from a male customer of the Internet cafe, the dispatchers in the command center began to receive calls one after another.
