In a frequently visited izakaya, Yui Saijo (Mayu Matsuoka), an appraiser from the Kotori Tourism Bureau, Masami Kira (Minami Tanaka) from the infirmary, and Iori Kiyama (Krei Takizawa) from the transportation department are watching the extremely popularA video of the mayor of Kotori Yuki, Yuki Baba Sono (Eishi).Ba Chang Yuan has a perverse personality, many fans, and many enemies.He plans to build a self-supporting welfare home for the elderly and will hold a public debate with opposition lawmakers to this end.

Due to the proposal of Satoshi Mitarai (Yu Tokui), the director of the Kotori Recreation Department, everyone in the department must participate in the security work of the racecourse during the period before the debate.In addition to Naoki Serizawa (Aoi Nakamura) from the Criminal Division and others, Masami Kira was also sent to participate as a medical officer.

Serizawa and others are working as guards at the racecourse garden video shooting site.When Ba Chang Yuan saw Kira, he said hello: “Looks quite energetic”.Baba Soon was originally a doctor at the same time as Kira was an intern.The two once agreed to change the medical world together, but now both of them have left the medical front line.

On the other hand, Saijo was invited to watch the fireworks by Adachi Junpei (Hakusu Hun) next door.Saijo refused at first, but Adachi proposed drinking and watching fireworks on the roof of the apartment. Saijo was attracted by the idea and agreed.After that, Saijo paid close attention to every message sent by Adachi.

When Ba Chang Yuan returned to the office, he found something unusual. It seemed that someone had come in. He rummaged through the computer and the files in the drawer.At this time, a masked man appeared from behind and beat the racecourse...!
