Synopsis

A major personnel reshuffle occurs within the Tokyo Metropolitan Police Department, with Nagashima Hideo being transferred to the Special Crime Investigation Task Force, prompting the recall of Sakuragi Izumi from her local precinct to work under Nagashima’s command. Simultaneously, other special task force members are reassigned to new departments, where each struggles to adapt to their new environments. Sakuragi finds herself partnered with Sergeant Takigawa, who possesses extensive knowledge, experience, and exceptional investigative abilities. Although Takigawa remains unconvinced about his partnership with Sakuragi, he provides her with strict guidance and training.

 

One day, a series of suspicious fatal accidents begins occurring throughout the jurisdiction. Families of the victims repeatedly approach the local precinct, requesting a reinvestigation of these incidents, which leads to the convening of an investigative conference. Each accident appears to be caused by defective products from various companies, resulting in fatal outcomes. However, Takamine Ryoko (Yamaguchi Sayaka) observes peculiar patterns in these cases: the deadly accidents occur consecutively over specific periods before suddenly stopping completely, and every victim dies without exception, suggesting deliberate manipulation behind these incidents. This leads the team to suspect a potential “serial corporate extortion” scheme.

 

The investigation team realizes that if their theory proves correct, new incidents will likely emerge soon, creating urgency in their efforts to identify and apprehend the perpetrator before more lives are lost. The case presents a complex challenge that tests the newly formed partnership between Sakuragi and Takigawa while exploring themes of corporate responsibility, criminal exploitation, and the methodical approach required to solve cases involving multiple jurisdictions and victims across different industries.
