Lee Soon-gyu, who wanted to say something, was stopped by Kim Taeyeon, turned his head to see that the picture of "Signal" had appeared on the TV, and then he didn't say more, squeezed his ass behind the sofa, and looked at the TV with a pillow.

At the same time, I don't know how many eyes from the entire peninsula were fixed on their TVs, whether they were expecting, delighted, or questioning, looking at the "tvN 10th Anniversary Special Project" and "Signal" logo fonts that appeared in the middle of the screen, and began to concentrate and watch.

"The stream flows slowly."

"It will also converge into a wide sea."

As rock singer-songwriter Jung Cha-sik sang the OST "You Let Me" in a deep and vicissitudes of life, close-ups of the three protagonists appeared on the screen side by side, and the dynamic silhouettes of Ji Kyung-won, Kim Hye-so, and Cho Jin-woong's three faces sounded

Followed by some close-up clips of each protagonist in the play, but these pictures are not coherent, just a freeze-frame picture is continuously together, with a special aging effect of the age, with some grainy shots, which immediately give people a very thick, cinematic texture.

"Not bad......"

The opening of a TV series can show its difference, and many viewers can't help but nod their heads lightly and secretly admire in their hearts when they look at this prelude.

As the OST ends and gets to business, with the 'July 29, 2000' on the screen, the story of "Signal" began to be written 15 years ago and began to be officially unfolded before the left and right audiences.

In the playground of Jinyang Primary School 15 years ago, there was a burst of laughter, all the students were happily playing badminton, but there was a little boy squatting alone in the corner on the side, and did not participate in the activity, he picked up a branch and wrote and painted on the ground by himself, occasionally looking at the playground crowd with a little envy in his eyes, and the figure of the lonely figure seemed a little lonely.

This is because of a change in the family, which led to a big change in the personality of the young hero Park Hae-young.

At this time, a kind-hearted little girl with a pair of rabbit teeth, Kim Yun-jin, found the lonely Park Hae-young, this girl is very cute and cute, and she may also be a little socially phobic, she may be out of good intentions, or she may be happy to find a companion, drooping two braids and taking the initiative to come up, holding a badminton racket and smiling and inviting Park Hae-young to play together. This kind of cute practice before elementary school boys and girls made many viewers laugh along.

It's a pity that although Park Hae-young was a little moved, she didn't appreciate it out of the loneliness in her heart, and left without saying a word after glancing at her, which made the little girl Kim Yun-jin a little disappointed.

When it rained heavily at the end of school, many of the parents of the classmates came to pick up their children, and everyone else was almost gone, and it happened that only Park Hae-young and Kim Yoon-jin, who had no one to pick them up, were left in front of the teaching building.

Kim Yoon-jin didn't bring an umbrella, and looked at Park Hae-young who was holding an unopened umbrella in her hand with expectant eyes, but little Park Hae-young put the umbrella behind her back, her mouth was sipped together, and she couldn't open her mouth if she wanted to help her.

Because his umbrellas were broken, two of them were broken, and they didn't look good when they were propped up, and he was embarrassed to show them in front of each other.

Park Hae-young and Kim Yoon-jin glanced at each other, rushed into the heavy rain in each other's lonely gaze, and did not open the umbrella, allowing the rain to pour on themselves.

When he was about to leave, he looked back and saw that Kim Yoon-jin was picked up by a fashionable woman holding an umbrella, and he couldn't see the woman's face, only a pair of beautiful and conspicuous red high heels.

He estimated in his heart that this woman should be Kim Yunjin's mother, and he was a little envious in his heart, but he didn't think much about it.

But something unexpected happened.

When Park Hae-young came home and was eating ramen, he suddenly saw a news item urgently broadcast on TV:

"Flash, an elementary school student in Jinyang City, Gyeonggi Province was kidnapped on the way from school, and the police have launched an investigation into it......"

Looking at the photo of Kim Yoon-jin that appeared on TV, looking at her grinning with a pair of rabbit teeth and a bright smile, Park Hae-young was a little stunned.

Then the kidnapping case began to ferment wildly the next day, and soon the police investigation progress was broadcast on TV: "The suspect in the abduction case of Kim Yunzhen's child has been identified, and according to the threat letter and the fingerprints at the crime scene, the suspect is identified as Seo Hyung-jun, who is studying at a medical university ......"

Park Hae-young has been paying attention to the case because he witnessed the process of Kim Yoon-jin being taken away, and because he felt a lot of guilt because of the previous umbrella, and he was very anxious after seeing the photo of the young man Seo Hyung-joon, the suspect, on TV.

Because he knew that it was a woman who took Kim Yoon-jin and was wearing red high heels.

Because of what happened when he was a child, Park Hae-young has a strong sense of distrust of the police profession, he wandered in front of the police station for a long time with an extremely conflicted mentality, hesitated again and again, and finally remembered Kim Yoon-jin's smiling face, or puffed up, and walked into the police station nervously to tell them what he knew.

"The kidnapper is a woman!"

He doesn't know anyone either, and everyone he sees pulls each other and says the same thing.

But no one was very busy, hurried by, and no one took him seriously.

The next day, the bad news came, and the police found Kim Yoon-jin, who was smiling brightly a day ago and took the initiative to help him, turned into a cold corpse.

Park Hae-young was stunned again.

And many viewers were also stunned together, and the delicate feelings of such a beautiful elementary school student just now immediately turned into a cruel parting of life and death.

Some of the warmth generated by the beautiful lens language disappeared in an instant, and many people remembered that this was a crime and criminal investigation TV series.

The kidnappers disappeared after killing Kim Yunjin and tearing up the ticket, the police nationwide pursuit did not yield, and there was no progress in this case without further evidence.

But there are always people who remember all this, because the case is not closed, the murderer has not been found, Kim Yoon-jin's mother, with anger and grief, has stood in front of the police station with a photo of her daughter for fifteen years, calling on people not to forget and urging the police to pursue the murderer and handle the case.

It's a pity that the effect is very little, and after attracting a burst of attention at first, it gradually becomes dull.

And the only one who has always seen this mother's figure in his eyes is Park Hae-young, who has often come to the door of the police station because of guilt in these years.

The story starts here.

Fifteen years later, on July 27, 2015, with the narration of the reporter "The statute of limitations for the kidnapping case of Kim Yoon-jin, the three unsolved cases, Kim Yoon-jin, is about to expire", the grown Park Hae-young reappeared in front of the camera.

"The focus of the problem is on the subconscious, the trophy on the living room decorative cabinet, the picture on the table, or through a book in the bathroom, you can see the person's habits, and the subconscious."

In a café, with a white shirt, delicate short hair, just the right facial features, and a confident and condescending smile on his face, the adult Park Hae-young played by Ji Kyung-won instantly attracted the attention of all the audience as soon as he appeared, especially many fans who came to him couldn't help but widen their eyes and exclaimed in their hearts.

"Tsk, that's really handsome."

Kim Taeyeon, who was still immersed in sadness because of the little girl's death just now, lit up her eyes, and her head involuntarily poked forward a little, and she praised it.

Lee Soon-gyu pursed his mouth and didn't make a sound, but his expression looked obviously agreeable.

Although Park Hae-young hates the police as an adult, he chose to become a police officer for various reasons, and got the title of guard, and he is also a very good criminal psychology profiler.

But in his heart, he instinctively hated it, even though he became a policeman, he didn't take this job seriously, but became a gossip dealer in his free time, using his high-level mental profiling ability to analyze and deduce the scandals and black material of idol stars, and at the same time release the news to the newspaper.

Because of his extremely high accuracy of analysis, he has a small name in the industry and is also disgusted by many celebrities.

"You mean, that's what you know? How did you know that the two of them met at half past ten last night behind Xuanzhen Park? Trace? Wiretapping? You're not a half-immortal! ”

At this time, Park Hae-young was trading with an entertainment reporter who was familiar with him, and the middle-aged reporter was a little unconvinced of what he had just said, frowning and questioning.

Park Hae-young took out a tablet, pulled up a photo and showed it to the other party, chuckled, and said very confidently: "Ji Jingyuan and Kang So-ra have already spread a lot of news when they filmed a TV series together last year......"

"I know, it's "Unborn", and the section chief is very handsome." The reporter leaned forward and looked at the photo seriously, nodded and said.

“…… That's right, this is the home image of the apartment where Ji Jingyuan lived this time, and the photos and posters in the room are huge, right? According to statistics, this kind of person has a strong self-esteem, and it is very likely that he is extremely self-...... Kang So-ra may always contact him, but the two of them don't meet easily, so they will definitely pick a very important date......"

"What about time? Why half past ten? ”

“…… The time of the date also has a psychological effect mixed in, the next day at ten o'clock in the morning, Ji Jingyuan has a rehearsal for a large concert, according to this itinerary, he will get up at six o'clock in the morning, the sleep time he needs, and the time he needs to talk after meeting Jiang Sula, and the time period with the least number of people, etc., considering the above points...... It's easy to conclude that the date time is half past ten in the evening. ”

"Where? Why is it ...... Hyunjin Park?"

At this time, a close-up was given, and many viewers took a closer look and found that the photo in the tablet in Park Hae-young's hand was the same frame photo of the actor Ji Kyung-won and the heroine Kang So-ra in the press conference of "Unborn" last year.

This is obviously because the crew rubbed the popularity of last year's "Unborn", took the two leading actors to play tricks, and watched Park Hae-young played by Ji Jingyuan in the camera seriously analyze his love and dating, and he was very convincing, and many people couldn't help laughing.

It's the same as the real thing......

Just when Park Hae-young used her excellent analytical reasoning ability to find out the date and place of Ji Kyung-won, completely conquered the entertainment reporter, and was about to talk about the next business, he was suddenly interrupted.

Officer Cha so-hyun, played by Kim Hye-so, appears to beat the two heads and bring Park Hae-young back to the police station.

Because Park Hae-young was reported to the police and followed.

"Collect money? I'm sorry, but I never charge money for doing these things. ”

After being taken to the local police station, in the face of Cha so-hyun and the old policeman Kim Gye-chul's questioning, Park Hae-young smiled and looked at the other party without evasion: "You can check my bank account, I haven't received a penny...... Just like some people like fishing and some people like knitting sweaters, this is also my hobby. I use my abilities to collect hidden information and then share it with the public, is this also a crime? ”

“…… I bet on my neck, and among this pile of colorful cards, there must be the business card of Li Baoying's agent. ”

Although he was in the police station, Park Hae-young was not nervous, he confidently and strongly took the lead, and analyzed Cha so-hyun and Kim Gye-cheol in a few words, and directly pointed out that the reason why the other party handled the case so seriously was because he received the benefits of the agent of the artist Lee Bo-young, who was exposed to love by him before.

Although Cha so-hyun was later on the righteous side, satirizing him for still doing things like stalking and turning over trash cans as a policeman, but this few sides of his face just appeared, and the image of Park Hae-young's character stood up all of a sudden.

Outstanding ability, elite, self-confidence, handsome, with their own bottom line and persistence, and at the same time there is a fire burning in their hearts.

When many viewers saw this, they had a lot of good feelings about this actor, and felt that Park Hae-young's setting was very appetizing.

After a lecture, Park Hae-young was about to leave the police station and walk in the corridor, looking at the surrounding scene, he suddenly remembered that this was the police station that investigated the kidnapping case of Kim Yoon-jin 15 years ago, and he inexplicably recalled the scene when he was standing here by himself, helpless and anxious because everyone around him didn't believe him.

At this time, the picture revolves around Park Hae-young, the color slowly turns yellow, and the nostalgic atmosphere is highlighted, flashing back to the time 15 years ago, describing the police handling the case at that time.

And in 2015, Park Hae-young, who had left the police station, just walked out and found that his car was blocked by a truck, and he called to move the car but no one answered.

"Rustle...... Zila ......"

The sound was muffled, a bit like some kind of telegraph transmission.

At this time, the soundtrack suddenly became quiet and weird, and many viewers cheered up at once.

"Guard Park Hae-young...... Can you hear ME? I'm Lee Chaehan......"

"This is the Seonil Psychiatric Hospital you said, and in the cellar in the back, is the body of Seo Hyung-joon, a suspect in the Kim Yoon-jin abduction case......"

In the sound of being filled with electricity, Park Hae-young walked to the loading and unloading port of the truck, and was immediately stunned when he heard the sound coming into his ears.

Kim Yoon-jin...... Abduction ......"

He silently recited the name, and for fifteen years, this case and this name have been like a nightmare in his heart, imprinted there, lingering.

He followed the voice, hurriedly rummaged through a garbage bag inside, and soon found an old-fashioned walkie-talkie wrapped in a plastic bag, he took the walkie-talkie out, and started a conversation in a bit of anxiety: "Who are you?" What the hell are you talking about? What happened to Kim Yoon-jin's abduction case? Are you talking about the Good Day Mental Hospital......"

From the viewer's point of view, the camera of the drama is constantly switching, with images of Lee Jae-han in 2000 and Park Hae-young in 2015 flashing back and forth, and the two are engaged in an incredible exchange that spans 15 years through an old-fashioned walkie-talkie.

"Oh Mo!"

Seeing this scene, countless viewers felt creepy, and only felt that an ordinary crime drama was instantly dyed with a layer of fantasy factors that made people's hearts chill.

But at the same time, there is a kind of excitement in my heart, this wonderful setting makes many people's eyes shine, and it instantly shows very different characteristics from ordinary suspense criminal investigation films, which arouses the audience's infinite expectations.

This is the real starting point of the title "Signal".

Park Haeyoung asked a few words anxiously, but unfortunately he didn't get a clear answer and hung up the call, he had never seen such a bizarre thing, and when she drove away, she laughed at herself if she was too busy and hallucinated recently.

It's just that when he drove out of the door of the police station, he saw Kim Yoon-jin's mother standing there holding a photo of her daughter, and the memories of the past came to his heart, and the unspeakable complicated emotions resurfaced.

Communicating with friends at the police station, he shocked everyone again after discovering that this walkie-talkie had no battery, and remembered the news he had just heard, and decided to follow his own thoughts and went to the place he had just heard on the walkie-talkie, 'Shanri Mental Hospital'.

Sure enough, after some dark and scary exploration, he found a corpse in the cellar at the back of the hospital, and after being startled, Park Hae-young hurriedly called the police, and after DNA testing, it was found that it was indeed the body of the suspect Seo Hyung-joon.

The kidnapping case of Kim Yoon-jin itself is a well-known unsolved case in the country, and as the news of media intervention quickly fermented, this case that once attracted everyone's attention once again entered the public's field of vision, and countless people are concerned about the progress of the once unsolved case and who the murderer is.

But this also brought great pressure to the police, because the legal prosecution period of this case is less than 29 hours left, and it is exposed at this time, if the real culprit cannot be found out within the specified time, then the Jinyang Branch will become the laughing stock and the object of condemnation across the country.

After some weighing, Jin Fanzhou, the senior executive of the Jinyang Branch, decided to cover up the truth that Xu Hengjun was killed, announced the final conclusion of the murderer's suicide in fear of crime to the outside world, and took the initiative to walk out of the police station in front of countless media, and apologized to Kim Yunzhen's mother who had stood at the door for 15 years after a generous statement with superb acting skills and a generous statement.

But on the other side, Park Haeyoung couldn't bear it.

Forget about other cases, Kim Yunjin's kidnapping case is a shadow that will never linger in his heart from the beginning, and he can't help but think about it all these years.

If he hadn't been embarrassed at the time, he lent the umbrella to the other party and the two of them walked together, wouldn't this incident have happened......

For so many years, there has been a strong sense of guilt with him, but there is nothing to do about this unsolved case without evidence, and at this time, there is finally a turning point to catch the murderer, clear the haze in his heart, and let the little girl rest in peace, when the boss actually wants to cover up the facts, saying that the murderer committed suicide in fear of crime.

Park Hae-young, who has always been calm and confident, and doesn't care much about the identity of the police, couldn't bear it anymore, driven by guilt and a sense of justice, he became uncharacteristically anxious and excited, ignored Cha so-hyun who stopped him, and rushed out of the police station while Kim Beom-ju was still performing, and shouted loudly in front of countless reporters:

"Xu Hengjun was killed by him! It's the real murderer who abducted Yoon-jin and killed him! ”

This sentence was like a dazzling light that broke the night, and immediately attracted the attention of everyone around, and reporters flocked to it, with long guns and short cannons, and flashing lights that could not open their eyes.

Park Hae-young had already let go at this time, but in front of the camera and reporters in front of the camera, he still carefully told the true progress of the case, and finally said his speculation and profile of the real culprit:

"The murderer worked in the Seonil Psychiatric Hospital 15 years ago, after the age of thirty-five, he was about 165 tall, he could use a scalpel proficiently, and he was a nurse who had entered the operating room......"

"Take him away!" Cha so-hyun next to him shouted anxiously, and two policemen hurriedly walked up and wrapped his hand around him to take him away.

When he was pulled away by the police, Park Hae-young did not struggle, he looked at a recent shot, his eyes were sharp and sharp, and he shouted seriously and resolutely:

"Maybe you've lived these 15 years without guilt......"

"But now, you're done."

……

"Wow, that's a great act."

Countless viewers in front of the TV sighed.

Many people have been infected by this paragraph, and the depressed mood in their hearts because Kim Beom Joo wanted to cover up their true thoughts was vented by Park Hae-young's play, and they only felt refreshed, and at the same time, they were also somewhat moved by the abnormal Park Hae-young.

"When you look at Jingyuan's last look, I feel a little panicked."

Kim Taeyeon watched the TV tightly and sighed at Lee Soon-gyu next to her.

"Jing Yuan's acting skills are really good, really talented." Lee Soon-gyu, who hasn't spoken much, also nodded: "No wonder the director is so optimistic about him." ”

Comparisons are odious.

Park Hae-young was happy to shout like this, but the entire Jinyang Branch was dragged into the water by him, and there were only more than 20 hours left to handle the case, which made everyone's heads big.

However, Park Hae-young was not flustered, although he was impulsive just now, he also had a plan in his heart while shouting, his real intention was to let everyone who saw the scene just now through the media, and make the real murderer panic and make mistakes in a fierce way, and there were not too many nurses in the Seonil Mental Hospital back then, this case is so big, someone will definitely take the initiative to report it next.

Because there is really no time left, this is the only way to go.

As soon as the words fell, a report call came in.

The Jinyang Branch has already been set up for loving you, and the chief officer An Zhishou gritted his teeth and ordered to start an investigation.

The sound of various phones and BGM rang, even through the screen, the audience could clearly feel the anxiety of the situation at this time, the atmosphere had been set off very tensely, and everyone was clenching their fists and sweating.

Although most of the reporting calls were unreliable, despite all kinds of difficulties, with the efforts of everyone, the most suspicious target was still found, and someone was immediately dispatched to Seoul Youngin Hospital to bring back a very suspicious nurse Kang.

But after bringing it back, Park Hae-young thought that something was wrong, so she anxiously ran into the interrogation room, checked up and down and looked at this Nurse Jiang, but found that Nurse Jiang and his profile did not match at all.

Dressed in simple sheets, no lipstick, no manicures, no heels, and more importantly, not left-handed.

"It's not this woman......"

He spoke his judgment in some desperation, and all the police around him were silent

The picture flashed back, it turned out that the real culprit was a nurse surnamed Yin, after watching the report on TV, she changed the name tag on her locker and the nurse Jiang next to her, and then took the initiative to call the police, just to let the police catch the wrong person and delay this last time.

At this time, she was in a car near the police station, facing the mirror on the visor, wearing lipstick elegantly and leisurely, with the pride and reserve of a victor, quietly waiting for the prosecution period to pass.

"We must not end up like this......"

After the negativity, Park Hae-young forcibly calmed herself down, and after saying a word to herself, she began to analyze: "Whether it was the abduction case 15 years ago, or now, that woman has always been confident in her crimes, she dresses up fancy, thinks she is better than others, can manipulate and dominate others, and even the police ......"

“…… She must be watching from the vicinity at this time, she must be close, wanting to see our defeat with her own eyes......"

With that, he rushed straight out.

Although he has always been confident in his analytical ability, Park Hae-young is actually unsure of this analysis at this time, but if he always tries it, it is better than standing here, no matter what, he wants to use the last time to find the murderer.

And Cha Xiuxian also followed, but she did not blindly look for it, but directly called the traffic department, reported the license plate number and asked them to check the surveillance near the Jinyang branch after half past seven.

The two men rushed out of the police station one after the other, and at this time, it was raining heavily.

Walking through the crosswalk, crossing several intersections, and looking for a few storefronts, Park Hae-young stood in the middle of the street and was a little dazed and desperate, when he finally saw a back holding an umbrella, slender and familiar, although it had been so many years, but it was still imprinted in the depths of his soul.

He immediately ran wildly, rushed through the rapid number of cars, and stood in front of the woman when she wanted to leave quickly.

Fifteen years ago, I watched from afar in the pouring rain as you took my friend.

And 15 years later, still in the heavy rain, my hair is messy, my clothes are wet, but after all my strength, I finally stand in front of you, looking directly at your vicious, disgusting face.

The TV series should only write one chapter in detail
