Yu Amagi (Noriyuki Higashiyama), Yoshiki Ebisawa (Seiichi Tanabe), and Shin Aoyama (Takashi Tsukamoto) will be present at the scene. Makino, who died with a crossbow arrow stuck in his chest, is a national star whose Hollywood debut is scheduled for next year, and it seems that the media has already sniffed his death. There were two types of crossbows, real and dummy, for shooting, but Hamada said that he fired them without noticing that they were real. Was it just an accident, or was someone deliberately substituting it ...!?
According to Aoyama, there are 335 people in the studio, including employees, filmmakers, actors, and staff, and no one has gone out since the incident. With 335 suspects, Amagi sharpens his eyes, saying, 'There is a criminal in this studio ...'. We start questioning one by one, but everyone is suspicious and has a habit ...
