This view is becoming stronger and stronger, but the murderer is still unknown.Yukiko Makabe (played by Yuki Amami), who currently belongs to the Special Criminal Investigation Department of the Metropolitan Police Department, and the administrator of the Investigation Section 1, Seki Kajiyama (played by Tetsuji Tanaka), also learned the specific identity of the prisoner from Yuta Tsujimoto (played by Kohiro Tsunoda), the corporate publicity officer who contracted the project...

At the same time - Masato Kuramochi (Koshi Yamamoto), who is popular as Japan's first wheelchair anchor%, mentioned this serial murder incident in his reporting program to denounce the government.The audience criticized this condescending argument, but he remained indifferent... and even made provocative remarks to the prisoners in front of the camera.

Just then.Kuramochi transformed from a hacked anchor into a tragic anchor, winning the sympathy of the world.Not only was his biological father, Shingo Isogai (played by Ryu Raita), who lived with Kuramochi, murdered in his own home, but Kuramochi himself, the first discoverer, was also attacked!Moreover, the murder weapon was pliers...!? When the possibility that the same person committed the crime as in the previous incident surfaced, the Metropolitan Police Department officially decided to temporarily activate a special investigation team, the Emergency Case Response Team (commonly known as the intensive investigation), to investigate.Yukiko, Kajiyama, Tamagaki Matsuo (Tsubaki Tsukaji), Hishimoto Susumu (denden), Koishikawa Haruo (Kohinata Fumiyo) - the emergency members who went to New World gathered again to launch a search...

Following two national project officials related to the redevelopment plan, Shingo Isogai (played by Ryu Raita), the biological father of the popular anchor Masato Kuramochi (played by Yamamoto Koji) who provoked prisoners on the show, was also murdered in the same way. This is an unprecedented serial murder case.With many suspects, Yukiko Makabe (played by Yuki Amami) and other members of the “Emergency Interrogation Team” (commonly known as “Intensive Interrogation”) conducted intense interrogations and finally succeeded in eliciting a confession from the “real murderer”.But at the same time, the investigation also ushered in a new situation.“The real murderer” actually firmly denied the fact of killing Isogai.And... Kuramochi’s estranged wife Ritsuko (played by Mayumi Wakamura) gave a shocking testimony!

“I killed Kuramochi’s father, and my husband also knew it.”If this testimony is true, why did Kuramochi cover up his wife and pretend to know nothing?In order to reveal the truth as soon as possible and reliably, the members of the tight investigation, who had “special reasons”, began listening to “Kuramochi and his wife at the same time...

Investigating the suspected couple at the same time would bring greater confusion to the investigation.Kuramochi cleverly avoided the attack of intensive interrogation, but when he heard that Ritsuko admitted the crime, he showed an expression of surprise and confusion as if he really didn't know anything!On the other hand, Li Jinzi presented new evidence to prove his crime.Regarding the motivation, I started to think deeply...

Completely different testimony.Who is lying??And, what about the love that keeps the two together even after separation?still…….During the investigation with no exit visible, Yukiko made a certain proposal to the suspect in front of her.At the same time, the investigation turns into an ”unimaginable death battle%...!?

However, the body of Sho Domon (Katsuta Hatani), a mountain rescue team member who slipped and died during the search, was found near the scene...! And the results of the judicial autopsy showed that this unfortunate accident was probably a homicide.There were suspicious signs of beating on Domon's body, and his cell phone suddenly disappeared——.

What surfaced as an important reference person on the search line was Masayoshi Bushi (played by Shigeyuki Totsugi), the captain of the mountain rescue team who had been working with Domon before.However, Busan, who has saved many people's lives so far, is called “山神” and has also won the Fire Chief Award. He is an amazing person.Yukiko Makabe (played by Yuki Amami) and other members of the Emergency Case Response Investigation Team (commonly known as the Urgent Investigation Team) immediately launched an investigation, and Busan's attitude was very honest, which was simply a divine response.There is no doubt about the confession...

Under such circumstances, Yukiko accepted “Fuzai's confession” which was completely logical, and intuitively became suspicious, so she proposed to use induction interrogation to sway him.However, Kajiyama Seki (Tetsuji Tanaka), an administrator who graduated from the mountaineering department of the same university as Busu, immediately raised objections...!?

At the same time - Yuka, who finally regained consciousness, started to tremble for some reason!On the other hand, Kajiyama entrusts Yukiko and others with the task of investigating the incident, and heads to the mountains where the “incident” occurred...

On the other hand, the trial of Rena has been in a stalemate from the beginning.With an innocent smile like an idol, Rena appeared in the interrogation room wearing a black ruffled dress. She had a laid-back attitude from beginning to end, and her confession was also very ambiguous.Yukiko and Tamagaki Matsuo (played by Tsukaji Takemasa) who were in charge of the reception were also disrupted, and the time limit was reached in a blink of an eye.
