At the beginning of the film, three students are seen, one of whom is named Soy.
They enter a church and take a commitment while holding candles that they will die tonight.
They write their last note on a piece of paper and also put their blood on it.
Moreover, they take an oath while putting their hands on it, meanwhile, someone knocks church’s door
due to it, they get panicked.
On another side, we see a girl waiting for her sister Eon Ju outside the school
but then Eon Ju jumps from the roof and ends herself.
This makes her sister scared as well as sad and she starts crying loudly.
The next day, the three girls are shown in the school office along with Soy
who were making a plan to die last night but the three were alive.
The school principal was taking information from them about Eon Ju’s death
Soy was saddest of all, she becomes emotional and starts weeping while moving into the washroom
Eon Ju was a good friend of Soy and they used to spend time together
during this, we see Eon Ju’s soul standing outside the washroom staring at Soy.
She wants to come near Soy and touch her, she also calls her
but Eon Ju’s soul moves till Soy sees back.
Soy comes to the class but a few girls stop her way and start teasing her
they ask her about Eon Ju’s death but Soy remains silent and doesn’t answer them.
Meanwhile, Soy’s friend comes and scolds them, she takes Soy from there while holding her hand.
Now the three were standing in line at lunchtime
when an ill-mannered girl comes and starts teasing them again, she says I think Soy is hiding something
she must know something about Eon Ju’s death, she again starts questioning Soy.
On it, Soy’s friend slaps her and says don’t tease her again otherwise I will complain about you to the principal.
The next day, Soy was sitting alone in the library because she was still sad because of Eon Ju’s death
but then her friend comes and handles her.
Soy says last night I told Eon Ju about our death so I think she died because of us
as she loved me a lot so she died because I planned to die.
That means the three have made the plan to die but only she died.
They are still alive even though they should also have died. Now Soy was trying to sleep at night
she saw the vision of Eon Ju’s death how she die of jumping?
and there must be blood everywhere, Soy couldn’t sleep due to this.
The next day, Soy goes to Eon Ju’s funeral, Eon Ju’s sister tries to ask Soy while stopping her
tell me about Eon Ju why she ended herself? I know my sister, she never can do this
she promised me to meet that night so tell my why she did this?
Soy listens to her but leaves without telling anything, when she sat in the bus to reach home
she starts remembering the time spent with Eon Ju, how happy they were together
she becomes emotional while remembering all this and her eyes fill with tears.
The next day, the students of the school pray for Eon Ju in the church, for her soul’s peace
Soy goes to the place where Eon Ju died, she starts missing her words
about how they were happy together, here a past scene is also shown.
They have a deep friendship that they always promise to stay together always
Soy moves ahead while thinking this but her friend stops her and says we promised not to come here
then why did you come here? well, whatever, come with me. Saying this, she takes Soy with her.
Eon Ju’s soul was standing on the roof watching them while leaving
the next day, Soy was in the class and sees that her finger is bleeding
later, her hand was soaked in blood and seeing this, she gets scared and yells.
The girls watch her because of this but when Soy sees her hand again, there was no blood.
This amazed her, Soy was leaving the class and there were Soy and her friends names were written on the glass
and it was also written that those girls are hiding something about Eon Ju’s death
and they knew all the truth about it.
Seeing this, Soy’s friend suspects that rude girl that’s why she goes to her immediately and asks
why did you write our name and that nonsense? but she says I didn’t write and I don’t need to do this
maybe Eon Ju’s soul has written this.
At night, Soy meets her friends in the church and Soy says why don’t we tell the truth to everyone in the school?
so that none will ever tease us again but the friends get shocked and say no we can’t do this
because If we tell the whole truth then we will be sent somewhere else
and we will be defamed as well, none will respect us, what everyone will think?
On it, Soy agrees, then okay we will not tell anything to anyone.
They were leaving for home but one of them turns and sees behind again and again
when Soy and her friend ask what happened? who is behind? why are you watching behind?
She answers I feel like someone is chasing us
but her friend ignores while saying you are thinking too much about Eon Ju
that’s why you are feeling this so just put her out of your mind, don’t think too much about her.
Now another girl from this school tries to jump from the building
because the girls of her class tease her a lot and she couldn’t see any other way instead of jumping,
as she opens the window of her room to jump, suddenly, Eon Ju comes and stops her.
She throws her aside, slaps her and then strangles her neck and ends her.
At night, the dad of Soy’s friend was beating her a lot because he was drunk
he was beating his daughter because he felt she is not studying well,
because she got lower marks in the papers.
On the other side, Soy’s friend starts tearing her books with the help of a key
as she discovers that someone else got the first position and then holds the key,
here, we find out that the key is given to the student who got the first position every year.
Now because someone else got the first position this time so the principal asks for the key from her.
On it, she begs, “Please let me keep this key,” and we learn that Eon Ju, who died, was ranked #1.
Knowing this, Soy’s friend becomes furious and comes out
because she wants to get the first position like always.
Then she goes to the class to their other friend and sees her friend’s eye was hurt
because her dad beaten her brutally last night, her injured friend asks her to stay with her tonight
because my dad will beat me again but she doesn’t reply.
Now the friends move to the canteen for lunch
a few girls were spreading rumors that Eon Ju jumped from the roof because she was pregnant
hearing this rumor, Soy feels bad so she takes her friend out to talk.
From her this act, her friend feel that Soy has spread this rumor
but she denies it while saying I can’t do this ever because Eon Ju was a good friend of mine.
Their friend sees someone standing behind the tree when they were talking, she panics
but when she tells this to others and they see, there was none.
Soy was worried because of the rumor so she leaves
but a few girls again start teasing her while stopping her way and start asking about Eon Ju.
This makes Soy furious that she pushed them and leaves
meanwhile, Eon Ju’s younger sister comes in front of her and asks her about the rumor while crying.
She says I checked her whole room but didn’t get any clue that she will harm herself
but this time too, Soy leaves without telling her anything.
This makes Eon Ju’s sister sad and decides to find out why her sister jumped while reaching that roof
but she didn’t find anything when she moved to the roof due to it, she became worried.
She becomes so sad that she decides to jump from the roof
but Eon Ju’s soul saves her sister while pulling her.
When Soy’s friends enter her life, she devotes less time to Eon Ju, as depicted in a previous scene.
She spent most of her time with her two friends,
while before their arrival Eon Ju and Soy used to stay together always.
Eon Ju was feeling bad because of her diverted attention.
Soy also had a boyfriend those days and they used to like each other
they were happy together so they married secretly, it discovered after a few days that Soy is pregnant.
When Soy’s mother in law found out that her son married secretly and his wife is pregnant
she felt bad because she didn’t want this school girl to be her son’s wife and his baby’s mother
so she took Soy to the hospital and had her baby aborted.
This made Soy sad and when she told her husband about this, he starts fighting with her instead of supporting her
he says you aren’t a good girl, not capable of me, saying this, he divorces her.
Soy used to stay worried because of this that one day, she argued with Eon Ju
and they become angry. Now the scene shifts to the present
when Soy is swinging at night but she feels like Eon Ju’s soul is sitting on the nearby swing
whose face is soaked in blood, she gets panicked, falls down the swing and becomes unconscious.
The next morning, Soy was sitting alone in the class and that rude girl comes and pushed her
she teases her again and asks about Eon Ju’s death, she says I know you both were good friends
that you love each other but your friends couldn’t bear this, they enter in your friend deliberately
so that Eon Ju would stay worried all the time, wouldn’t pay attention to studies, wouldn’t get the first position
and your friend who got first position, gets first position like always
so that’s why you are responsible for Eon Ju’s death, she was worried because of you and died.
Soy feels bad to hear this so she leaves
Eon Ju’s soul comes when she left, she attacks that girl and holds her face
she tries to strangle her neck, Eon Ju’s soul was doing this because this rude girl was teasing Soy
so that Soy will become fed up with her words and harm herself.
After a while, Soy returns to the class but the girl was missing which amazed her.
Now the rumor that Eon Ju died because Soy started spending time with her friend while leaving her.
Soy was so touched by this that she became depressed and was thinking about it all the time.
She becomes so worried that she collapses her hand on a window, due to it, the glass breaks
while Soy’s hand was also injured and her hand starts bleeding.
Soy’s mother in law was going somewhere in the car, she was on a call and was looking happy
but then she starts feeling strange in the car and there was a painful voice
this voice was so weird and painful that it was pricking her ears
and she puts her hand on her ears but because of unbearble voice her ear drums burst.
Her ears start bleeding as well as her eyes, nose and mouth
This caused her so much pain that she died in agony.
Eon Ju’s spirit was responsible for her death because she had aborted Soy’s baby.
We find out Eon Ju is ending everyone who ever teased Soy or harmed her.
Now to trap Soy, Soy’s friend was saying to everyone in the school that Soy was also with Eon Ju that night
and they decided to jump together but only Eon Ju died
while Soy cheated on her and didn’t jump.
Saying this, she comes to the washroom and Eon Ju’s soul comes in front of her.
She was soaked in blood, she gets so scared that she falls aside.
After a while, she comes to the class and tells her friend about this
she says I saw Eon Ju’s soul in the washroom and she will not spare
but her friend doesn’t believe her because she think that it is just her illusion.
She comes out and again sees Eon Ju’s soul outside the window.
She panics and starts screaming, they all gather after hearing her
she says there is Eon Ju’s soul outside but when they see outside, there wasn’t Eon Ju’s soul
Eon Ju’s younger sister was standing there and after a while, she comes to the class to meet Soy.
She doesn’t question Soy about her sister but relaxes her because Soy was still worried.
From this, we can understand that Eon Ju’s soul told her sister the truth
now Soy’s friend who was seeing Eon Ju’s soul again and again starts beating Eon Ju’s sister
while holding her hair because she feels that she is scaring her as Eon Ju.
Seeing this, Soy stops their fight and calms them down, she asks Eon Ju’s sister to leave
Eon Ju’s sister agrees to leave
but says to Soy’s friend while leaving It would be better to tell the truth to everyone.
This makes Soy’s friend furious that she pushes Eon Ju’s sister out of the class
and closes the door. Now the injured friend of Soy who saw Eon Ju’s soul again and again
hides in the washroom being scared but then her friend comes and handles her
while making her understand saying look, you are getting scared of Eon Ju’s soul for no reason
she is dead and can’t come back but her friend was scared and says let us tell the truth to everyone.
Her friend denies and feels she will ruin everything if she will go out so she leaves while locking her in the storeroom.
Soy was alone in the class and sees a girl’s hair coming out of a locker
as she pulls the hair, the locker opens and there was that rue girl’s body in a bad condition.
She was soaked in blood and was kept in the locker while breaking and twisting her.
Eon Ju comes to Soy’s friend who was locked in the storeroom and scares her, she gets panicked and fell aside
while her friend who locked her in the storeroom was taking her computer class.
Suddenly, she sees Eon Ju’s soul coming out of the computer,
she gets so scared that she fell down but then stands up immediately and goes to the store to check her friend.
She finds her friend in the washroom instead of there,
when she asks, she says Eon Ju’s soul has brought me here
and now she wants us to reveal the truth to the whole school otherwise, she will do bad to us.
Saying this, she comes to the school roof to jump while pushing her friend
because she was fed up with being scared of all this but her friend comes and says look, don’t be silly
why are you doing this? she says I can’t live while suppressing the truth inside me
and my dad also doesn’t love me, he beats me whenever he want and Eon Ju scares me of not telling the truth
that’s why it would be better for me to die and saying this, she jumps and dies on the spot.
Soy saw her doing this so she comes to her and starts weeping while putting her body on lap
meanwhile, many students and teachers come there and there was a crowd.
Now because Soy was in a trauma because of all this so the teachers handles her.
After it, she was sent home. Their friend was watching her dead body from a distance
even she was her friend but didn’t come near but she was happy that one of the girls knew their truth was no more.
Then she goes to the principal office to take the key back that was taken by the principal
she was looking for the key but suddenly, Eon Ju’s sister comes in front
the key was in her hand and showing it, she says tell me the truth.
She doesn’t say anything but attacks her head with something and makes her faint.
After this, she goes near her and says your sister Eon Ju was mad that she died instead of Soy
saying this, she goes to the church and sets the note on fire on which they wrote the pledge
so that there will not be any evidence of that night.
After this, she goes to Soy and says Eon Ju is behind our friend’s death so now she will not spare us,
now get up and go to the church to apologize to God for our mistakes.
Soy comes to the church with her but as they move to a room, her friend comes out and locks the door.
She locks Soy Inside, she reveals that I made a plan to die just to end you
because I didn’t get the first position just because of you means that night Soy’s friend thought of cheating on her
means the three plan to jump but when it comes to jumping, they will not jump and will let Soy jump.
Now we are shown the past when all this happened,
Soy and her friends were sitting in the church and were discussing their life problems.
They made a plan to die, now a day before executing the plan,
Soy’s friends made a plan that we would just accompany Soy to jump but would not jump to harm ourselves
likewise, only she would die and none would suspect and our task would be done.
Now Soy’s friend attacks her in the present time, she strangles her neck and tries to end her
later, she hung her, she was doing this so that everyone will think that she harmed herself.
The last person, Soy would also be ended who knows that night’s truth
and none will ever discover anything about that night,
meanwhile, Eon Ju’s sister comes and we see that Eon Ju has possessed her.
She escapes Soy with her powers and hangs Soy’s friend
then pulls the wire so hard that her neck is suppressed and she dies.
After it, the day is shown when they must die,
they make a plan for night and Soy tells Eon Ju at day time that today she will die with her friends
Soy was weeping while telling this but Eon Ju relaxes her saying you are a good friend of mine
and I love you a lot, I can’t live without you so I am with you in this plan and will die too.
The night when they were taking the pledge to die,
someone knocked on the door and it was the scene we saw at the beginning.
We were not shown that who were on the door but here we find out that there was Eon Ju at the door
she came in the end because she was late.
She poured her blood on the paper and the four decide to die together
even Soy forbids Eun Jo to do this but she said I want to be with you even after death.
She doesn’t listen to her and then the four stand on the roof while holding hands to jump
but one of Soy’s friend cheats and leaves Eon Ju’s hand, due to it, Eon Ju was falling down
but by the time Soy notices this, it’s too late to help her, even if she clutches her hand
but till then she died. We discover Soy’s friends wanted Eon Ju and Soy to die together
and they escape but only Eon Ju dies here.
Eon Ju’s soul and Soy are shown standing on the roof in the present time,
they show love for each other and Soy apologizes to her being emotional
But when she hugs Soy, Soy feels she loves me so much that she decides to jump as well
and thinks of staying with Eon Ju as they promised. Now she holds her hand and stands on the wall
but as she is about to jump, Eon Ju’s sister comes and saves her.
Here, seeing her sister, Eon Ju says to Soy, stay alive instead of dying
and take care of my sister as an elder sister, Soy promises her don’t worry I will do the same
she will never have any complaints, Eon Ju’s soul becomes happy to hear this and leaves from there forever.
After it, we see Soy’s husband who got married again
as they move in the lift we the girl who looks like Eon Ju means Eon Ju has possessed her.
She has come here to exact revenge on Soy’s husband for what he has done to her.
Here concludes this movie.
