The film begins by showing a man named Erik, who has just finished making out
with a woman named Talia. Erik then goes to the bathroom to clean himself up and take a shower.
Meanwhile, Talia heads to the living room to get a drink and listen to the song,
but at this moment she has feeling that someone is watching her. It turns out that she is right about
her feeling because a few moments later, she is startled by the presence of someone from behind.
When Erik gets out of the shower, something unusual seems to catch his attention.
And it turns out that the reason he looks that way is because he sees the words “you're next",
written in blood on the mirror. It doesn’t stops there because as he looks down,
he is shocked to see Talia's dead body. But his shock doesn't last long as he is suddenly caught
by someone from behind, who kills him right away. The scene then moves to a husband and wife who
are on their way to some place. The husband named Paul, and his wife, Aubrey. They are heading to
their vacation home in the suburbs, where they'll be hosting a family reunion with their children.
When they arrive to their vacation home, Paul notices that the front door to their house is
not locked, and he bet the workmen left the door open last time they were there.
Aubrey then gets straight into the dining room to clean it up,
before welcoming their children with their partners. Meanwhile, one of Paul's children
named Crispian, is on his way to the house with his girlfriend, Erin. They are now talking about
Crispian's parents' wealth, and Erin looks so excited to meet her boyfriend's family.
Aubrey who is still cleaning up, is startled by a sound and shaking that comes from upstairs. She
then tells Paul about it, but her husband looks calm and tells her to wait outside first. Paul
then rushes upstairs to check if anyone is there. After calling out several times and checking in
every room, he discovers that there is no one on the upstairs of the house. But he suddenly
heard the sound of something falling in a room, prompting him to go and check it out.
And he is then surprised by the arrival of Crispian, who has already arrived at their house.
After they go downstairs to meet Erin, we can see that the door to the room is slowly opening.
Crispian then introduces Erin to his parents, and his parents invite them both into their home.
On that night, they will be just resting and sleeping while they await the arrival of the
other Crispian's siblings. The next day, Crispian who has just woken up is greeted by his brother
named Drake, and his wife, Kelly. Crispian and Drake often act like children while recalling
their childhood memories. After that, Erin walks into the kitchen and offers any help but Aubrey is
all sets. Aubrey suddenly remembers that she has run out of milk, and asks Erin to go to
their neighbor’s house named Erik to get some. Erin then takes a picture of the three family
members, and tells Crispian that his mother told her to go to their neighbor's house.
When Erin arrives at Erik's house, she tries to call out Erik but there is no respond. As we all
know, Erik has been killed by someone before, and the song in his house is still playing.
Later in the day, Paul's other children arrive to the house with their partners.
They are Aimee and her boyfriend, Tariq, as well as Felix, and her girlfriend named Zee.
They later greet each other, and introduce their partners to Paul.
Following that, Aubrey then invites them to dinner together with the dishes she has prepared
for them. While having dinner together, they ask about all of the siblings' partners' backgrounds
and jobs. At this moment, Drake and Crispian are suddenly arguing and getting angry at each other,
because Drake always looks down on Crispian. When the environment has becomes such a fuss,
Tariq suddenly notices something is not right. He tries to check on it,
and suddenly a sharp arrow flies through the window.
The fact that Tariq is dead causes them all to panic, and their planned dinner together
today has now turned into a nightmare in a matter of minutes. In this chaotic situation,
Drake immediately prevents his mother from being targeted, but he is hit by an arrow on his back.
They try to call the police but there is no signal, and Felix speculates that the killer
may have installed a cell-phone jammer near the house, preventing them from calling the police.
As the situation becomes more tense, Erin begins to show her other side by
ordering everyone to move to another room, and use the chairs as shields.
She then tells Kelly to hold Drake's wound, so it wouldn't bleed a lot and make it even worse.
After that, Felix suggests that one of them run out to the car and go get help, and he
asks who's the fastest runner. Seeing all of them are arguing about who's the fastest runner,
Aimee then volunteers to run outside. Their plan is that as soon as Felix opens the door,
Aimee will be running quickly and the killers not gonna expect her to be coming out full speed.
Aimee then runs and bursts through the door,
but unfortunately…
Well, it turns out that their plan is fatal because right in front of the door, there is a
garrote wire that severely slices Aimee's throat. Seeing them all getting hysterical,
Erin then takes the initiative to lock all the windows and doors, preventing the killer from
entering the house. She also explains that if they text 911, some of the police station may
receive it as voicemail, so if they even have 1 bar, they can at least send a text.
Crispian doesn't expect Erin to be able to handle herself so well in such a difficult situation.
Aubrey is taken into a room by Paul, where she can rest and calm down.
Unfortunately, after Paul has left Aubrey, they have no idea that one of the killers is already in the
room. He slowly comes out from under the bed and kills Aubrey right away.
As a result, they all rush to Aubrey's room after hearing her scream. The moment they walk into the
room, they see Aubrey who has been killed and the killer leaves the same words on the wall, which
is You're Next. At the same time, when Erin closes the kitchen
window, her hair is suddenly pulled by the psychopath,
but Erin manages to fight back by stabbing the killer's hand into the wall with a knife.
Paul on the other hand, is so devastated and saddened by the loss of his beloved wife in
such terrible condition. They then take Paul out of the room to calm him down. Kelly who is still
in the room, covers Aubrey's body with a cloth, but she begins to feel like someone is watching
her. As she tries to look under the bed, she sees that the killer is still hiding there.
Kelly then becomes very scared, where she can't think straight anymore and runs out of the house.
At the same time, she doesn't realize the killer who is on standby outside is following her.
Kelly keeps running until she reaches Erik's house, where she attempts to scream for help but
gets no response at all. And her efforts are in vain when the killer suddenly appears from behind,
and punches her in the face causing her to bounce into the house. At this very moment, Kelly asks
Erik for help, only to discover that Erik is no longer alive. The killer then gets inside
and kills Kelly with his ax right in her face. Meanwhile, inside the house, Erin asks Zee to
hold Drake's wound, and Crispian then says that he is going out to get the car so they all can
get out of this house. At this point, Erin begins to sense that one of the killers is still at home,
so they decide to hide the unconscious Drake's body while waiting for Crispian to get the car.
After that, Erin goes to the kitchen to heat some water in preparation for later.
She then looks at the window and rushes to get various kitchen tools to defend themselves.
But the killer suddenly shows up and pushes Erin until she falls with the tools she brought.
The masked killer also takes Kelly's dead body with him, and attempts to kill Erin. However,
the situation is reversed where Erin manages to kill the killer instead.
Felix and Zee are surprised and didn't expect that Erin can act like that.
After that, Erin opens the killer’s mask, but they doesn't recognize the killer's face at all.
In the upstairs, Paul returns to check the room he wanted to check earlier, and finds bottles of
drink and foods there. But the lights suddenly go out, forcing Felix and Zee to look for Paul.
His father then explains that this wasn't a random attack, and they've being watched for days.
Unfortunately, the killer appears out of nowhere and kills Paul right away in front of his son.
Well, it is at this point that everything is revealed, where Felix and Zee are just
looking calm as it turns out that the killer was an order from the two of them.
Erin, on the other hand, is surviving an attack by one of the psychopaths.
And then the awakened Drake suddenly appears, indirectly attracting the killer's attention.
Seeing the killer walking towards Drake, Erin quickly runs toward the psychopath and
stabs his back with a screwdriver. After the killer runs away, Drake asks where Kelly is,
but Erin doesn't want to tell him the truth. Erin then asks Felix if Paul is alright,
but Felix lies and tells that his father's condition is fine upstairs.
After that, they all starts looking for tools to defend themselves from the killers.
Erin then covers Kelly's body so that Drake wouldn’t know that Kelly had been killed.
She also begins to devise a plan by setting up a nail trap for the perpetrator to fall into.
Zee then asks where Erin learns all of this, and Erin tells her that she grew up in a survivalist
compound. Plus, her father was also paranoid, and wanted her to be able to take care of herself.
Meanwhile, in the basement, Felix tells Drake that his girlfriend Kelly has been killed. He then
kills Drake after realizing that Drake's emotions have gotten out of control, which of course
part of his plan too. Drake as his own family doesn't expect his brother to do such a thing.
Zee, on the other hand, tries to find a way to kill Erin, but she is unable to do so due to
the circumstances. After that, Erin then makes her way upstairs, only to find out that Paul is dead.
At the same time, the killer who is already behind her tries to kill her. Erin realizes
this right away, and is still lucky to survive even though her leg is injured after jumping out
of the window. Following that, the killer keeps chasing Erin forcing her to run into the forest.
While hiding in the tree, Erin tries to release the broken glass stuck in her thigh. But the
killer manages to find her and shoots an arrow at her. As a result, Erin who can no longer run
normally is now forced to return to the house. She then hides in a hidden space behind the curtain.
Just as the killer is about to enter the window, he realizes that Erin had set a
nail trap for him earlier. So he seems to think that Erin wasn't smart enough at this,
and he gets hit by Erin's another nail trap that is put right under the window.
Felix and the others then head downstairs, and he starts scolding his hired killers for having
their plans screwed up over just one girl. Erin who is hiding in a hidden room,
finally finds out that all of these killers are acting on the orders of Felix.
In other words, Felix does all of this in order to have sole control over their parents' inheritance.
But suddenly they hear Erin's phone ringing, and it turns out that her emergency message has been
received by the police as voicemail. The killer then approaches the space where Erin is hiding.
As the killer is about to open the curtain, Erin quickly hits him and runs from the house.
Once she is able to get out, she runs back into another room through the window.
Soon after, one of the killers is trying to look through the window,
and Erin shows up and stabs the killer in the head with a knife.
Well, there's only one killer remaining after she manages to kill this one.
Erin then takes the killer's ax and
sets a trap by placing the ax on the door, where an ax will fall and kill anyone who opens it.
Felix, who is still on the lookout for Erin, asks for the crossbow so that he can kill Erin with his own
hands. After setting a trap, Erin then runs into the basement and destroys all the lights there.
When the killer comes, he is drawn towards Erin's camera flash.
Seeing the killer has
been blinded by the camera flash, Erin then comes out and breaks his skull with a log.
When she comes out of the basement, Felix shoots her with the crossbow, but he misses the shot. Zee
then continues to chase her, while Felix goes to his car to turn off his cell-phone blocker.
Inside the house, Erin is having a fight with Zee, which is followed by Felix's arrival. Felix
who has just arrived at the kitchen is doused with water by Erin, but the water is no longer hot.
Zee then bites Erin's hand and Erin gives her a pan blow in the head.
While Zee and Erin are fighting, Felix wakes up and stabs Erin in the back,
but Erin manages to fight back by taking a blender and hitting Felix with it.
Erin then uses her ultimate move by putting the blender on Felix's head, shredding it and turning
it into a smoothie. After that, Erin takes the knife stuck behind her and stabs Zee in the head.
Not long after, Felix's cell phone rings and Erin picks it up without saying anything, and she hears
Crispian's voice asking if it's all over. Well, Erin finally finds out that
her own boyfriend is also one of the masterminds behind this murder tragedy.
The moment Crispian enters the house, he realizes that Erin is holding Felix's cellphone.
At this moment, Crispian tries to persuade Erin and explains he didn't meant to kill
her in his plan, as they needs someone with no motive like Erin to see what has happened here.
Plus, with the treasure left by his family, they will be able to live happily and get
out of their broke-life. As Crispian keeps talking about how happy they'll be after this,
Erin keeps her gaze fixed on him, and kills his boyfriend by stabbing him in the neck.
At the same time, a police officer finally arrives and immediately shoots Erin in the shoulder.
The police officer then reports to his team, and requests for backup to come there.
After that, he attempts to enter the house, but it looks like bad luck will fall on him,
as he will pass through the door that Erin had set up as a trap. Erin tries to stop the cop,
but it is too late. And with that, the film ends.
