Synopsis

At the venue of an international environmental energy summit, a kidnapping occurs, and the victim is later found murdered. The weapon used in the killing turns out to be a handgun previously confiscated by the police.
 
Wangan Police Station is assigned to handle the investigation, but a policy is put in place that withholds all information from investigators, including Aoshima (Oda Yuji), forcing them to proceed without any shared intel.
 
As the situation escalates, a second murder takes place, and in the third incident, Mashita (Yusuke Santamaria)’s son is kidnapped.
