This drama is adapted from Keigo Higashino's novel of the same name. It tells the story of Shigeki Nagamine (played by Yutaka Takenouchi), a father who is dependent on his daughter. After his daughter was brutally murdered, he became a murderer in revenge.Shigeki Nagamine has been raising his daughter Ema alone since the death of his wife. In the blink of an eye, his daughter is already in high school.One night, Emo didn't come home after going to work.When Changfeng saw his daughter again, she was already a cold corpse with traces of abuse on her body.A few days later, Changfeng received a mysterious phone call, telling him the name and address of the murderer who hurt his daughter.After much hesitation, he decided to go find it.After sneaking into the family's house, he discovered a video recording his daughter being brutally tortured to death.At this time, one of the murderers happened to go home, and Changfeng killed him in a rage.Then began revenge against another murderer.His daughter's two killers will not face the death penalty because they are minors.As a father, is Shigeki Nagamine's act of avenging his daughter right or wrong?

Nagamine accidentally spills ketchup on himself, and Ema, his daughter, rushes to help him wash his clothes.After cleaning, Emo hurried out to go to work.Nagamine went out to the balcony to dry, while Ema was going home after the day's work.However, colleagues warmly invited her to join them for dinner.After the meal, Emo hurried home.At the same time, Atsushi and two others were drinking in the car, and they rated the girls passing by.

Ema passed by them, caught their attention, and became their target.Atsushi and others followed her and forced her into the car in a no-man's land.Ah Cheng gave her drugs and made her unconscious.Nagamine sends a message asking why Emo hasn't come home yet, then calls her, only to find that her phone is turned off.Atsushi and others took Emo to a room, and Cheng's Nagamine called him and asked him to drive back quickly, otherwise the police would be called.Cheng wanted to do so, but Atsun stopped him.Atsushi also slapped Cheng and told him to act like a man and not be afraid.Cheng was worried that Chang Feng would call the police, so he finally agreed to drive the car back and promised to bring 100,000 yen back next time.

Nagamine called Emo's colleagues, who said they lost contact after eating.Nagamine was worried about Emo's safety and decided to go out and search for him personally.Atsushi also injected Emo with a drug, causing her to wake up instantly.Ema tried to escape, but couldn't escape the control of Kuaiji and others.Kuai'er used a camera to record his sexual assault on Emo.Nagamine asked the police for help, and the police said they would step up patrols to find Ema's whereabouts.


The next day, Acheng received a call from Kuai'er and came to his home.However, the concierge was locked and he could only check through the window and found that Ema was ruined and seemed to be dead.Cheng was very panicked, handed the money and car keys to Kuai'er and left in a hurry.Kuai'er warned him not to call the police, otherwise he would also become an accomplice.At night, Atsushi and Kuaiji drove Emo's body and threw it into the river.The body was later discovered by police and an investigation was launched.


Nagamine received a call from the police and was devastated to learn that Ema had died.The police asked him for relevant details, but he only cared about whether Emo was a homicide.The police said that the investigation has not yet been completed and they need to wait for the identification results.Nagamine denounces the incompetence of the police and firmly believes that Emo was raped and murdered.The police had actually identified the suspects, but since they were underage, it was difficult to characterize the incident, so they concealed the truth from Changfeng.


Nagamine returned home and cried sadly as he looked at Emo's clean clothes.The special investigation section of the police station investigated Emo's case and found that her cause of death was acute heart failure and that stimulants still remained in her body.Cheng watched the TV news, which reported the news of Emo's death, and fell into deep thought.He holds Ema's dropped cell phone and recalls the scene when she was forcibly dragged into the car.Media reporters interviewed Changfeng one after another, but he did not want to pay attention to them.


Cheng found out that his car was exposed on the Internet and was suspected to be the car that killed Emo.He hurriedly called Kuai'er to ask, but Kuai'er put all the blame on him.Kuai'er threatened Cheng that even if the police came to the door, he could not confess them, otherwise he would die of overdose like Emo.Ah Cheng wanted to call and surrender, but ultimately chose to give up.


Nagamine was lying at the place where Emo's accident occurred and received a voice message, revealing that the murderers of Emo were Kuaiji and Atsushi, and gave him Kuaiji's home address.Changfeng came to Kuai'er's home and opened the door as prompted by the voice message.He looked around and found photos of the other murdered girls and Ema's clothes.Then the rape video taken by Kuai'er was discovered. Changfeng was furious and cried sadly.At this time, Atsushi came to Kuai'er's house. Changfeng picked up a knife and stabbed Atsushi, asking about Kuai'er's whereabouts.Atsushi also realizes that this man is Ema's father, and expresses his satisfaction with Ema's experience, giving him full marks.These words angered Nagamine, and he stabbed Atsushi continuously, causing Atsushi to die on the spot.

After the police discovered Atsunya's body, they quickly set up a cordon area.Atsushi also had more than thirty wounds caused by kitchen knives, and fingerprints on the murder weapon provided clues to solve the case.What is striking is that before Atsushi was killed, the last person he came into contact with was Kuai'er, but Kuai'er's current whereabouts are unknown.Motomura, as a friend of Atsuya, became the first person to discover the body during the search for Atsuya.He revealed to the police that Atsushiya and Kuai'er had kidnapped young women and raped them. This crime was confirmed by the police and relevant video evidence was found.

During the investigation, Officer Mano asked whether only Kuai'er and Atsushi were involved in the case, and specifically mentioned Cheng.However, Cheng's mother said that Cheng was not at home.Meanwhile, Kuai'er chooses to burn Atsuya's photo after seeing it.During further investigation, the police discovered a video of Emo being raped and dying of an overdose of stimulants.When the police searched for Changfeng, they found that he had disappeared and took the shotgun with him.Fingerprint comparison results showed that Nagamine's fingerprints were consistent with those on the murder weapon, making Nagamine the main suspect in Atsushi's murder.Because Changfeng possessed a shotgun and might be emotionally unstable, the police decided not to reveal the identity of the real culprit to the media for the time being.However, the police are confused about how Nagamine learned about Atsaya and Kuaji's motive for raping and killing his daughter.After Acheng's father learned of the police's intention, he was thankful that he allowed Acheng to go home and taught him how to respond to police inquiries.

Officer Mano then found Kuai'er's mother, hoping that she could provide clues about Kuai'er.While Nagamine was searching for Kuai'er's whereabouts, the police received his handwritten letter, in which he admitted to killing Atsunya and expressed no regrets, while looking for another murderer.The police's promise to keep the contents of the letter confidential was broken by media reports, causing dissatisfaction with the police chief.Nagamine expressed his deep longing and anger for his daughter Emo in the letter. His determination and actions won the support of many netizens.In the process of Nagamine's escape, he recalled every moment with Ema, and finally settled in Wakako's B&B.

Changfeng and Hejiazi returned to the B&B together, and Hejiazi expressed heartfelt thanks to Changfeng for his help in restoring the photos.The news on TV was still showing Shigeki Nagamine's report. When Wakako's eyes fell on Shigeki Nagamine's portrait, she couldn't help but froze.After several days of pursuit and investigation, Changfeng finally discovered Kuai'er's hiding place.At the beginning of a new day, he left the B&B without hesitation and embarked on a journey to find Kuai'er.Cheng tried to sneak out of the house, but his mother, worried about his safety, tried to stop him.However, Acheng resolutely pushed his mother away and walked out resolutely.

During an in-depth investigation by the police, they discovered a suspicious woman who had a close relationship with Kuai'er - Murakoshi Yuka.When Kuai'er disappeared, she was also missing.At this time, a taxi driver named Natsumura walked into the police station, and his daughter also suffered the same fate as Ema.When Nimamura saw the video of his daughter being raped, anger and grief instantly surged into his heart.He lost control for a time and wanted to personally avenge his daughter, but was stopped by the police in time.

Changfeng followed the clues and came to the B&B where Kuai'er had stayed, but it had become a ruin.It turned out that the B&B was burned down in a fire.At the same time, Wakako secretly entered Nagamine's room with complicated emotions. She opened his computer, but unexpectedly found a video of Emo being tortured.She was shocked. At this moment, Nagamine returned to the room and saw Wakako watching this heart-wrenching video.

Nagamine returned to his residence and unexpectedly discovered that Wakako was watching the video of Ema's murder.He begged Wakako, hoping she would give him some time to deal with the matter instead of calling the police immediately.Changfeng tried to leave the B&B, but was stopped by Wakako.Hejiazi came up with a solution. She drove Changfeng to a remote residence, which was inaccessible.She asked Changfeng to stay here temporarily and said she would not call the police.

Wakako asked Nagamine how to find the murderer of his daughter. Nagamine revealed that he only knew that the murderer was hiding in a B&B in Nagano. He asked around and investigated one by one.He told Wakako that she could always call the police if she changed her mind, but he didn't want her to get involved.Wakako returned to the car and fell into deep thought.

After returning to the B&B, Wakako's father noticed that she looked panicked and felt worried.At the same time, newspaper reporter Odagiri came to Nimamura and tried to get information about his daughter, but was strongly resented by Nimamura.When Odagiri showed Kuaiji's photo, Nimamura became emotional.On the other hand, Mano and Takashi discovered that there was an abnormal number in Cheng's recent call history, and they asked Cheng whether it was Kuai'er's phone number.Cheng admitted this, but his concealment behavior confused Zhenye and Takashi.They began to monitor Cheng's phone calls, and Cheng agreed.

The police tried to investigate Kuai'er's mother's bank account to find Kuai'er's whereabouts, but were rejected.Later, the police said it didn't matter whether Kuai'er was found or not, which made Kuai'er's mother shaken, and she eventually provided her bank account information.At the same time, Kuai'er and Youjia's life seems to be leisurely, but there is a dispute when Youjia teaches Kuai'er to use chopsticks, and Kuai'er loses control and beats Youjia.He Jiazi sent meals and information about nearby B&Bs to Changfeng.Nagamine is bewildered by Wakako's help, and Wakako reveals her own tragic experience of the death of her son.She blames herself for misdiagnosing her son's pneumonia and is still reluctant to throw away his toys.She understood Changfeng's feelings of losing her child, and revealed that she also came to this B&B through her daughter's guidance.

The police still failed to find Kuai'er, and Takashi proposed to publish Kuai'er's photo and issue a wanted order.However, Mano believes that Kuai'er is still underage and it is inappropriate to do so.Mano recalled a similar case in which a group of gangsters killed their companions and threw the bodies into the river.When they were arrested, they did not know the seriousness of their crimes and did not even apologize to the families of the deceased.This makes them commit crimes even more brazenly.Cheng's father accused Cheng of not taking the initiative to tell the police about Kuai'er's contact with him.Cheng felt angry and tried to strangle his father, but fortunately his brother and mother stopped him in time.

The next day, Changfeng received a new voice message informing him of Kuai'er's specific location.Kako went to find Nagamine but found that he was missing.She found Changfeng at the station, and he told her that he seemed to have found Kuai'er's location, but would not reveal the specific location to avoid her being implicated.Suddenly, a policeman appeared in front of them and asked passers-by.Wakako pulled Nagamine back and told him that he would personally pick him up tomorrow.The police then came to the B&B, and Wakako's father discovered that the person on the wanted notice was very similar to the guest who stayed at the B&B not long ago.Police stepped up searches of the neighborhood.

After Wakako hung up the phone with Changfeng, she immediately decided to go to the abandoned B&B in person.When she arrives at the scene, she finds Manano and Takashi searching around.She observed her surroundings nervously, her heart filled with worry.At the same time, Catfish Village is also anxiously looking for Acheng's whereabouts.When he found Acheng, he angrily took him into a taxi.Niuchun revealed his identity to Cheng and expressed his grief and anger at his daughter's murder.Ah Cheng was confused and frightened by the situation in front of him.

Accompanied by Kako, Changfeng began his journey of revenge.They met Wakako's father on the road, and he angrily asked his daughter why she was involved in such a dangerous incident.Changfeng expressed sympathy for his misfortune, but he firmly stated that his determination for revenge would not waver.Wakako stands firmly on Nagamine's side, hoping to prevent him from taking the path of crime.

In order to escape the pursuit of the police, Kuai'er appeared in front of Hejiazi and Changfeng.Changfeng immediately took out his shotgun and prepared to pursue Kuai'er.They ran deep into the forest. Changfeng tried to shoot Kuai'er, but due to the obstruction of the trees, his shot missed the target.Police heard the shotgun blast and rushed to the scene.Changfeng hurriedly hid in the grass while being pursued by the police.He sneaked away while the police were not paying attention.

Wakako met the injured Nagamine on the roadside, and she immediately took him away and bandaged his wounds.Changfeng expressed his gratitude to Wakako for his help.Wakako tries to persuade Nagamine to surrender, hoping that he can live for Emo's memory.After careful consideration, Nagamine decided to surrender and promised not to disclose Hekako's information to the police.However, after he received a voice message, he hesitated and eventually picked up the shotgun and ran out.Kako tried her best to stop him, but in the end she couldn't change his decision.

Ah Cheng received Kuai'er's call and felt nervous and angry.Kuai'er asked him for money on the phone and revealed that he had been shot for the first time.However, the entire call was monitored by the police.The police used this clue to guide Cheng to lead Kuai'er to Central Park for arrest.

Catfish Village has been secretly monitoring Acheng's house. He originally planned to follow Acheng, but he did not expect that Odagiri also accidentally joined the action.Since Acheng was protected by the police, Catfish Village had to temporarily give up the tracking plan.

Under the careful planning of the police, Mano planned a route for Cheng to ensure that Kuai'er could step into the trap they set.Cheng went to Central Park as instructed, but Kuai'er never showed up.The police began to suspect that Kuai'er might have sensed the danger.

At this moment, Kuai'er suddenly called Cheng and claimed that he had arrived at the designated place.Ah Cheng looked around, but didn't find Kuai'er.Kuai'er told Cheng that he was in the International Building and asked him to go upstairs to find him.Acheng reluctantly agreed to this request at Manano's suggestion.

As Cheng walked towards the International Building, the police followed him in batches to ensure that everything was under control.However, when Cheng arrived at the corridor of the International Building, Kuai'er suddenly appeared and stopped him.At this time, the police discovered that Changfeng had appeared in Central Park, and Catfish also mysteriously appeared in the International Building.

Kuai'er threatened Acheng to take out the money, but Acheng suddenly apologized to him, which confused Kuai'er.At this moment, Niucun rushed towards Kuai'er with a kitchen knife, shouting his name.Unfortunately, Natsumura accidentally fell down and dropped the kitchen knife to the ground.Kuai'er quickly grabbed the kitchen knife and stabbed Niucun hard. Niucun fell to the ground instantly.

This unexpected situation caught all the police off guard, and they quickly dispatched to prepare to arrest Kuai'er.However, Kuai'er took Cheng as a hostage, while Odagiri recorded the entire process on his mobile phone.Upon seeing this, Chang Feng hurried over and saw Kuai'er holding Acheng hostage. He raised his shotgun and prepared to shoot.

The director urgently ordered the police not to irritate Kuai'er and ensure Cheng's safety.Kuai'er took Acheng into the lobby of the International Building, and He Jiazi also rushed to the scene.She was surprised to find Changfeng aiming his gun at Kuai'er.The police acted quickly and asked Changfeng to put down the shotgun.At this time, the three parties fell into a tense confrontation.

Cheng took the opportunity to tell Kuai'er that he had never regarded him as a true friend, and even hoped that he would die soon.After hearing these words, Kuai'er put down the kitchen knife in his hand.However, Changfeng approached Kuai'er step by step with his gun raised.Kuai'er had no fear in the face of death, but Changfeng hesitated at this moment.Wakako's voice came, begging Nagamine not to do anything stupid.Nagamine was struggling in his heart. He wanted to avenge his daughter Emo, but he couldn't bear to see more innocent people hurt.

Just when Nagamine was about to shoot, Takashi shot decisively and knocked Nagamine to the ground.The police quickly arrested Kuai'er, but Kuai'er happily told Takashi that it was hard work.This scene angered Mano and he beat Kuai'er severely.

Later, Wakako was taken back to the police station for investigation.She asked whether the police officer who shot Changfeng would be punished by law for the killing.She had deep doubts about fairness and justice: For the same act of murder, why are some people punished by the law, while others can get away with it?

After careful consideration, the police team leader decided not to punish Takashi.He believed that Takashi's shooting was to prevent the continuation of Nagamine's criminal behavior and that it was self-defense.However, this decision failed to completely calm Wakako's inner doubts and dissatisfaction.

The police have yet to find out who leaked the information to Changfeng, causing him to know the arrest plan in advance.Mano suspected that someone within the police deliberately leaked information to interfere with the arrest operation.However, the police team leader believes that the police act in accordance with laws and regulations. Although the law sometimes makes mistakes, the police must act in accordance with the law.

When Odagiri returned to the newspaper to review the manuscript, he felt very hesitant about Nagamine's article reporting.She didn't know what to do with the article, which was so controversial and sensitive.Cheng came to the river bank with flowers and cried to confess his past mistakes and regrets.Wakako returned to the B&B and saw the eyes left by Nagamine. She put them together with the photo of her son and silently prayed that they could find true justice and fairness.
