Signal Long-Unresolved Incident Investigation Team Theatrical version

The film is a film version of the Japanese drama of the same name adapted from the 2016 Korean drama "Signal". In Tokyo in 2021, a senior government official died in a traffic accident caused by an out-of-control rental car on the highway. Sakurai's long-term unsolved incident investigation team headed by Sanzhi suspected that the incident was carefully planned. In 2009, political affairs officials died in traffic accidents in Tokyo. At that time, the police announced it as an accident, but Dashan was the only one who doubted the true nature of the incident. When the time reached 23:23, the wireless communication machine that was impossible to connect to sounded again! In order to save Japan, which may be threatened by bioterrorism, events in the "present" and "past" are involved in a deeper conspiracy. And can Saegusa and Sakurai successfully meet Dashan in the present?
