In the future society, human beings have developed a device that can access the memories of others. Originally, the tool was developed only to treat people with mental illness, but stepping into someone else's memory meant a glimpse into his life. Because of this, this technology is gradually being used in some uncontrollable areas. What kind of challenges do people encounter?

Is this technology a blessing or a disaster?

Xiaoxiong is a scientist, and he invented this device that can read memories. The human brain is like a giant memory, from small to large memories are stored in different partitions, and their devices can teleport a person's consciousness into another person's brain, which can then read their memories as if they were a recreation of a scene.

The main thing about this is that the device is able to detect which memories are real and which are virtual, thus avoiding the person being tested from disturbing the results by making up lies on the fly.

In order to develop this machine, Xiaoxiong almost went bankrupt, and even owed a lot of foreign debt. Now that his wife is pregnant, he desperately wants to give his wife and children a stable life. It just so happened that at this time, an investor approached Xiaoxiong and offered to bear his follow-up research and development costs, and also gave him a large amount of remuneration, provided that he made concessions and applied the equipment to fields other than medical treatment.

Originally, Xiaoxiong was still a little worried, but when he saw the number on the check, he immediately agreed. When they returned home, they bought their wife a pearl necklace, and they were finally able to move out of their humble rental house.

However, when his wife knew the truth, she had a big fight with him, what if the subject of the test did not agree, what if it was used in an illegal field? Their behavior was no longer just a moral issue, but no matter how hard she tried to change her husband's decision, they continued to debug the equipment for the time to come. There will be a lot of blind spots in people's memory, that is, places that cannot be remembered, and they will mark these areas with red X.

When there is an unimpressed character, Xiaoxiong will replace it with the image of an assistant. The highest configuration in the equipment may be the system sound of the female star. When their consciousness enters the subject's brain, the system will retrieve memories from different time periods according to his instructions, and then synchronize this memory to an external monitor, so that people can see the picture intuitively. In a blink of an eye, it was time to meet with the investor, Xiaoxiong took the equipment to an empty garage, but when he learned the identity of the other party, Xiaoxiong immediately retreated, and it turned out that the investor turned out to be the American police.

Recently, they arrested a suspect named Anthony, according to the clues that the police have, Anthony found out that his girlfriend was cheating and shot her, but the police did not have key evidence in their hands, so they wanted to borrow their equipment to see if he really killed someone. It is certainly not the suspect's subjective will to use the method of snooping on memory to handle the case, which is also the reason why Xiaoxiong refuses.

However, the police said that Anthony participated in the test voluntarily, and he could not remember what happened, hoping to use the device to restore the scene at that time. Since the other party was voluntary, and the police spent a lot of money, Xiaoxiong really had no reason to refuse, so he agreed.

There are so many memories stored in the brain that they need a reference point so that they can quickly locate the memory they want to retrieve.

The police took out a report letter, and at two o'clock in the morning, someone saw his girlfriend dead in the car by the bridge. After an investigation of the scene, the police extracted Anthony's fingerprints and murder weapon from the car, and Xiaoxiong only needs to return to the time of the crime to know what happened at that time. After everything was ready, the assistant implanted a chip in the back of Anthony's head, and Xiaoxiong's consciousness would enter the other party's brain through the chip, and according to the information provided by the police, they came to the night of the crime, and he saw Anthony rushing into his girlfriend's room in a hurry. After a fight, Anthony approached his girlfriend step by step with a pistol, and finally the scene went black, the gunshot rang out, and the girlfriend fell to the ground and died.

The system immediately analyzed the scene and found that the authenticity of the memory was as high as 95%, which means that the girlfriend was indeed killed by Anthony. With this evidence, the police smiled with satisfaction, and the case was basically over. Just when everyone thought it was over, the accident suddenly happened, and the assistant clicked out of the system, and their consciousness did not return to their bodies.

This system was supposed to be tested for another six weeks, just in case, Xiao Xiong deliberately left a back hand, when the normal way could not be exited, they could dissolve the chip, and force the shutdown to let Xiao Xiong's consciousness return to the body.

I thought this method was foolproof, but after the chip dissolved, Xiao Xiong still did not wake up, because the system was turned off, people could no longer get in touch with Xiao Xiong, which means that Xiao Xiong's consciousness was trapped in Anthony's brain forever. Four years have passed in the blink of an eye, and Xiaoxiong has been traveling in Anthony's memory.

From childhood to adulthood, he even memorized some fragments of dialogue. On this day, Xiaoxiong was watching the scene where Anthony repaired his father's car when he was a child, and he had watched this scene more than 400 times. Dad would ask little Anthony to hand him a wrench and go to the fridge to get a beer. But what people didn't expect was that when Anthony went to get the beer again, he actually looked back at Xiaoxiong, which shocked Xiaoxiong very much, people's memories are fixed, what is the scene of the boy looking at himself?

In order to find out, they played the memory over and over again, but the boy never looked at him again. The boy saw himself at four o'clock in the morning on July 15, and they wanted to know what Anthony was doing during that time. By scanning Anthony's recent memories, he was looking through the photos sent by his father, and when he saw the dog, Anthony's expression changed slightly, and Xiao Xiong instantly understood.

If Anthony is recalling a certain memory, and Nobita happens to be there, then the consciousness of the two will intersect.

Seeming to see hope, Xiong began to look through Anthony's memories to find the one he remembered the most. It turned out that Anthony was an addict, and in order to raise money for drugs, he actually started his father's idea.

One afternoon, Anthony and his accomplices stopped his father with a blindfold. However, the father is not easy to mess with, and in the course of the fight, the accomplice snatches the wallet and escapes, while the father rips off his son's mask. Anthony's guilt instantly welled up in his heart, and he wanted to explain it to his father, but he didn't know how to speak. This past was very painful for Anthony, and naturally it became the memory he recalled the most.

In order to meet him again, Xiaoxiong keeps this memory day after day. It wasn't until two weeks later that Anthony finally saw him. Xiao Xiong hurriedly identified himself, hoping that he would be aware of his existence. Anthony was shocked to see this, he couldn't understand the phenomenon, so he left in a panic.

After a day of cooling, Anthony returned to this memory again, although surprised by Noxiong's presence.

But the facts are in front of him, and he also wants to find out the truth. Xiao Xiong's consciousness has been trapped here for more than four years, which means that his body has been in a vegetative state for four years. Xiaoxiong wanted Anthony to tell his wife Xiaoshi about his situation, and he knew that this kind of thing was difficult for people to believe, so he confessed a few secrets that only he and his wife knew.

That night, Anthony called Xiaoshi, and in order to gain her trust, Anthony told the small details of her relationship with her husband, which no third person would ever know. Xiaoshi collapsed in an instant, is her husband really alive?

The next day, Dash arrives at the prison, where she wants to verify their existence in person, so she asks Anthony what her husband calls her. If the two could communicate, she would know the answer. Anthony immediately travels to that memory, but memories take time, and just when Xiaoshi is about to lose patience, Anthony gives the answer, which is a crucial breakthrough for them. With his wife as an external response, he can find a way to get himself out. Xiaoxiong's consciousness can talk to the system, indicating that the chip is still in Anthony's body, as long as the device is restarted.

By removing the chip from Anthony's body, Xiao Xiong may be able to get out of here. In order to achieve this purpose, Xiao Shi began to run around. She first found Xiaoxiong's assistant and asked him to do the test again. Later, Xiaoshi approached the police officer in charge of Anthony's case and promised to give the device to the police after the test was completed, in exchange for one day of Anthony's parole.

Anthony transports them to another memory of his own. This is the scene when he is in love with his girlfriend, and the relationship between the two is very good, although they have only been dating for four months, they both regard each other as the only one in their lives. How could Anthony possibly kill his girlfriend? Before the test began, Anthony called his father and said he was going to do something good, but his father sneered at him. Since Anthony took drugs, his father has been wiping his buttocks, and even after his girlfriend was killed, his father helped deal with it, and he never had hope for Anthony at the scene, Anthony, who hung up the phone, was very angry, and he secretly vowed to prove his innocence to his father.

In the blink of an eye, it's time for the test, and because Anthony can keep communicating with Xiaoxiong, the difficulty of this connection will be much lower. The assistant only needs to establish a specific frequency and then ask Anthony to say which memory the little male is in, and once his location is located, his consciousness can be extracted.

At this critical moment, Anthony suddenly put forward a condition, he wanted Xiaoxiong to find out what happened on the day his girlfriend was killed. Whether it's for his girlfriend or to prove it to his father, he must know the truth. They were very puzzled by this request, the case had been found out four years ago, it was Anthony who shot and killed his girlfriend, and his memory was very real. However, Anthony doesn't think so, the reason why he confessed his guilt was completely out of guilt for his girlfriend, and even now, he doesn't know why his girlfriend was killed. Without Anthony's help, it would have been impossible for him to leave, so he agreed.

In order to recreate the scene at that time, Xiaoxiong asked him what unforgettable things happened during his time with his girlfriend. Anthony said that his girlfriend was an addict like himself, and the two had a lot of fun when they first came into contact with contraband. But Anthony gradually realizes that their actions are actually killing each other, so he wants to stop it, but his girlfriend can't stop at all, until one day, his girlfriend quietly leaves without even saying hello.

When the two met again, the night his girlfriend was killed, Xiao Xiong asked him to recall as much as possible what he had seen that night.

In order to get more clues, Xiaoxiong also followed to this memory. Because so much time had passed, Xiao Xiong's memory had become blurry, and he only remembered that when he came out of the room, someone knocked him unconscious from behind. Xiao Xiong pulls down the intruder's hat and finds that the person is using the image of an assistant, which means that Anthony has completely forgotten what the other person looks like.

Xiao Xiong knew very well in his heart that Anthony must have noticed this person, otherwise he would not have left a figure with a hat. The key is how to help him recall everything, and while Xiao Xiong is looking around, he stumbles upon a tattoo magazine on the floor, and everything around him is blurry, but this magazine is very clear. This shows that Anthony's memory is not lost, but only lacks a starting point.

For example, if he forgets what he had for dinner, but remembers one of the steaks, he can use the steak as a starting point to recall the other foods in the dinner. Following this method, Anthony gradually recalled what he had seen when he woke up, including the man who had attacked him.

It turned out that this person was the drug dealer who robbed his father with Anthony, and the time when he attacked him was very close to the time when his girlfriend was killed, it seems that this matter is absolutely inseparable from him.

Anthony schemed and knocked the police officer on duty unconscious, then grabbed his rifle and went straight to the drug dealer's house. The drug dealer didn't know his intention at all, and thought that his good brother thought of himself for the first time after he was released from prison, but as soon as he invited Anthony in, the other party took out a pistol, Anthony asked him why he killed his girlfriend, and the drug dealer who saw the other party could only tell the truth, he was indeed at the scene that night, but his girlfriend's death had nothing to do with him, Anthony didn't believe him at all, if he didn't kill the person, then why was he at the scene?

The drug dealer said that his girlfriend was addicted to drugs, and Anthony could not satisfy him, so he had to come to himself. His girlfriend had already betrayed himself for medicine, which was the reason why he left Anthony. While the two were talking, the drug dealer's accomplice rushed up at gunpoint and took control of the situation. The drug dealer shot Anthony in the abdomen, but he underestimated the opponent's combat prowess. After snatching the pistol, Anthony first killed his accomplice, and then began to track down the drug dealer. Because of his injuries, Anthony's movements gradually become sluggish, and if he dies, Xiao Xiong will disappear from this world.

After some psychological struggle, he finally gave up on tracking. Holding on to his last breath, Anthony found Xiao Shi, and as long as he told him Xiao Xiong's location, he could remove the chip and let Xiao Xiong's consciousness return to his body. But at this critical moment, Xiaoxiong suddenly disappeared from his sight, which was a side effect of Anthony's weakened consciousness, and for the transfer to be successful, they had to meet in the same memory scene.

When Xiaoshi came to prison, she brought her daughter, and at the last moment of her life, Xiaoxiong would definitely take another look at her daughter. As he had guessed, the two finally met in the reception room of the prison. Anthony used one last force to relay this signal to Xiao Shi, and Xiao Shi activated the device to teleport Xiao Xiong back.

In the end, Xiao Xiong came to visit Anthony's father, and when looking through old photos, Xiao Xiong happened to see the dog in Anthony's memory, this dog was very stupid, and he couldn't even understand a simple sitting command, but his father denied it, this dog was not stupid, he was a show dog, and he sold it for a good price at that time. When you repeat something many times, your child will believe it. His father kept calling him a stupid dog, and Anthony took his word for it.

This statement shocked Xiao Xiong very much, if the dog's memory is wrong, then is it true or false that he killed his girlfriend? Back that night, Anthony received a breakup text message from his girlfriend, he hurried to his girlfriend's house, and when he just walked in, he saw his girlfriend standing in the room desperately with a pistol. The torture of contraband and the control of drug dealers made her completely lose hope in life. After expressing her apologies to Anthony, his girlfriend committed suicide with a bullet.

It turns out that Anthony is really not a murderer, because he failed to save his girlfriend, Anthony fell into deep self-blame, he once thought that his girlfriend was killed by himself, but if one thing is repeated many times, people will believe it.

Xiao Xiong lowered his head regretfully, and inadvertently, he found that the self on the back of the photo was exactly the same as the self who reported Anthony in the first place.

It dawned on Xiaoxiong that it was Anthony's father who sent his son to prison with his own hands, but why did he do it?

My father said that he was also an addict and that he had quit his addiction in prison. In order to prevent his son from going berserk on the streets, the father used the same method. Life in prison was hard, but at least it kept him alive. They didn't say a word, their father's original intention was because of love, but it was also because of this paranoid love that it led to Anthony's tragic end.

This is the end of the story, and the only thing that disturbs people's eyes is Anthony's intricate memory. What really happened that night? Was his girlfriend killed by him? In fact, there were three people at his girlfriend's house that night, and the first one to arrive was Anthony, who came to his girlfriend's house after receiving a breakup text message, so as to see him kill himself in front of him. Perhaps it was excessive grief, or perhaps because of self-blame, Anthony fell into a coma. The second one to arrive is the drug dealer, who has been controlling his girlfriend, which is one of the reasons why his girlfriend is on a desperate path. That night, the drug dealer came to her as usual, but as soon as he entered the room, he saw his girlfriend's body, and it happened that Anthony woke up at this time, and the drug dealer was worried that he would not be able to explain, so he hid in the dark and knocked him unconscious, and then slipped away.

When he saw his girlfriend's body and his unconscious son, he thought that his son had caused another accident, so he took his girlfriend's car and body to the bridge, and then wrote a report letter to the police.

He hoped to use this method to make Anthony reform, but he didn't know that it was his prejudice that drove his son to a dead end. Although memory extraction is dressed in the shell of science fiction, the whole story is about human nature. Everyone in the film has knots and tries to untie them in their own way.

Anthony's life was very bad, he did all kinds of drugs and robberies, his father thought that sooner or later he would be on the streets, and even Xiaoxiong thought he was a murderer after reading his life. Only Anthony himself knows that he is actually atoning for his sins by doing this, and it was he who led his girlfriend to a point of no return, which ultimately caused his girlfriend's tragic death. The guilt in his heart made him repeat over and over again, it was he who killed his girlfriend, so that in the end even he believed this memory. In the past four years, Anthony quit drug addiction, repented seriously, and hoped to change everyone's opinion, but his father suspected that he was dead and difficult to change just because he was too thin, so Anthony wanted to prove to him urgently, and the turning point in Anthony's growth when tracking the drug dealer could prove his innocence if he was caught. However, he promised to help Xiaoxiong get him out of there, and after some psychological struggle, he finally chose the latter. It was this decision that made him understand what true salvation is.

Anthony's father, who was once an addict and later successfully detoxified in prison, believes that prison is the only place that can save Anthony. He used his own way to help his son, but he ignored his son's true feelings, and finally Anthony died of hatred. Has the knot in my father's heart been untied? I don't think so.

Xiao Xiong is a scientist, and the war caused his father severe psychological trauma, and psychology did not help him come out of the shadows, so Xiao Xiong developed this device, hoping to heal the pain of patients by understanding their past. But after experiencing this incident, Xiaoxiong understood a truth, memory is just a microcosm of a person's emotions, and what can really heal the trauma is not the cold data on the machine, but love and care.
