The film begins with a scientist undergoing a synthetic experiment in his research lab.
In the beginning of the film, we noticed a massive mouse in a cage, which appeared to be an unusual mouse.
The rat appeared to have become alike as a result of any chemical reaction.
The scientist is seen with his wife, Linda, as the scene shifts.
The scientist discusses his job with his wife.
Here we learn, Linda was a doctor, and she was enraged with her husband,
Because he is sometimes so preoccupied with his work that he doesn’t care about Linda.
Meanwhile, Linda receives a call from the hospital, requiring her to leave.
Her husband goes into the lab after she has left. Because his laboratory was close to his home.
When he arrived, he was surprised because the mouse wasn’t in the cage.
As he watches this, he is shocked and takes his rifle from the drawer.
Suddenly, the mouse appears, his size like that of a human.
After putting his gun away, the scientist tries to relax him.
Because the mouse appeared to be rather aggressive.
Meanwhile, the mouse attacks him and ends him ruthlessly.
The scene turns to a couple, and the husband’s name is Allen.
He’s a geologist, but their relationship wasn’t going well between them.
As a result, she divorced Allen and moved her belongings from there.
Later, Allen arrives at Linda’s house with his assistant, Julie.
The place of her husband, the scientist’s death.
Because they were summoned by the police to assist them in their investigation.
A female Sargent says I don’t believe this scientist is eliminated by a human.
The senior officer says, that according to Linda, when she returned from the hospital,
She comes to know about her husband’s death. They arrive in the scientist’s lab after hearing this.
They discover the scientist, Linda’s husband, dead body.
The rat has ruined his body, after horribly eating body.
After seeing the dead body in such a deplorable condition.
Julie becomes quite concerned and exits there.

The senior officer, seeing the dead body in such a state, said,
I believe so, and he is murdered by any bear or wild animal.
While hearing this, Allen declares that the bears are not permitted to enter the city.
And wild cats don’t like to live with humans.
After taking the samples, I can make any suggestions.
Later, they begin to investigate Linda together.
Linda is being interrogated by the senior officer about what happened that night.
Meanwhile, Linda claims that I spent the entire night in the hospital.
Linda was sneezing while speaking, as we can see.
As a result, the officer starts to suspect her.
He believes Linda is concealing something from them.
Linda is informed by the senior officer that Allen wants to take a sample of your clothing.
Linda consents to provide the samples.
After giving her the card, the senior officer says to Linda,
Please call if you have any other information.
After leaving, Allen informs the senior officer that he believes Linda is shocked by her husband’s death.
I don’t believe she has anything to hide from us.
According to the senior officer,
With the scientist’s dead body at the crime scene,
I see several scattered files,
Which could suspect that those files were scattered by Linda to find anything,
And she is undoubtedly concealing something from us.
A girl appears in the next scene, bringing trash to the dustbin.
In the meantime, she hears a strange noise coming from behind her.
When she glances behind her, she notices the huge rat.
The young lady makes numerous attempts to escape but she falls down while running.
The rat attacks her and ends her as well in a brutal way.
Linda calls Allen late at night and informs him that she has information regarding the case.
As I’d like to inform you. That’s why she calls Allen to her house,
Linda takes Allen to the lab after he arrives.
She informs him that when she arrived here that night, she discovered some chemicals.
She further claims that my husband has never permitted me to visit this lab.
Allen claims that you should have told the officer about everything instead of me.
Allen begins to investigate these chemicals later.
He discovers the growth harmonic, a radioactive material, in this place.
My husband used to experiment on rats and rabbits in this lab, according to Linda.
Later, Allen takes photographs of the area, and Linda takes him into her home.
Both begin to drink, and it is during this time that Allen notices Linda’s mother’s picture.
Allen starts questioning Linda about her.
My mother, Linda claims, eliminated a long time ago.
She was a cancer patient, after all.
Linda says, “By all means, I’m willing to accompany you on this case.”
Because I want to arrest my husband’s ender as quickly as possible.
She starts questioning Allen about his wife later on.
Allen says, now we’re divorced, we live separately from each other.
When Allen arrives at the police station the next day, the officer begins telling him about the girl.
Last night, the girl was ended by a giant rat. The officer claims that the girl, like the scientist, was murdered.
Allen informs them that he paid a visit to Linda’s house the night before.
There, I learned that her husband experimented on rats in his laboratory.
It’s possible that the failure occurred as a result of a problem with the experiment,
The rat might change into a creature.
The rat might have ended the scientist and the girl.
The senior officer becomes ragged at Allen.
Why did you go to Linda’s place without informing us?
Because she’s now in our circle of suspicion, it’s probable she’s behind it all.
We should put the city on lockdown, according to Allen.
As a result, we should be able to catch that huge creature, the giant rat, very soon.
When the officer hears this, he says, “No, we can’t put you on lockdown.”
We don’t know anything about that creature and don’t have any evidence.
People would be terrified, and there would be turmoil everywhere.
People will be terrified of a huge rat roaming the streets.
Later, Allen arrives at Linda’s residence with his assistant, Julie.
As a result, he could try to warn her by telling her about the giant rat.
Allen begins to enter the house on his own.
Linda was nowhere to be seen in the house.
Meanwhile, he calls Linda’s number and discovers that she is not at home.
She’s left the house and gone somewhere else.
Allen hears a disturbance from the upstairs room during this time.
He tells Linda that something is at your house while she is on the phone.
Allen enters the room after getting his weapon.
The rat comes, knocking him down. and hurts Allen by rubbing his back with his long nails,
Allen manages to get out of the room. From there, he goes out with Julie right away.
Both arrive at the hospital later, and the officers begin their investigation into Allen.
What happened to him, and how did he get hurt like this?
According to Allen, a giant rat attacked me there.
It was the size of a bear. I guess the rat considers that house his own because
He comes there for that reason.
Now we must look into how he was created and how he grew to be so enormous. How could he be ended?
The senior officer tells that we’ve 24 hours and we’ve to capture him and have to end him.
Later, he calls Allen and asks him to put his all time and effort into this case.
Don’t bother anything else than this job.
Linda later arrives at the hospital to meet him and begins inquiring about his health.
Linda tells him that if he enters the house, the rat may attack and end him.
Allen takes her to his place after hearing this.
On the other hand, we observe a girl who visits a mechanic to get her car repaired.
Because the mechanic was alone in his garage, he had to go to fix her car.
When the mechanic was working on the car, a rat wandered in.
After attacking the mechanic, the rat ends him as well.
Because the girl was in his cabin, she had no idea what was going on outside.
When she returns to her car after a while, her foot has been trapped.
Meanwhile, she notices the rat eating the mechanic’s dead body.
The girl feels terrified of what she sees and begins to flee.
In the meantime, the rat has caught her and is eating her legs.
The girl hits him with the hammer during this time.
Meanwhile, the rat starts eating her hands and, after a while, ends and eats the girl.
The next day, while Allen is at home, he is called to the senior officer’s office.
He tells Allen that last night, the rat ended and ate a mechanic and a girl.
Allen claims that I’ve already suggested putting the city on lockdown and to inform the public about the rat.
The officer claims that it is simple to state but difficult to carry out.
The situation is now deteriorating. Our grip on the case is slipping.
That is why we are sending this case to the FBI.
The officer expresses gratitude for his help in this matter.
Allen becomes concerned after hearing this directly comes to Linda.
He tells her everything and tells her that the rat must be caught by us together.
Later, they both start to think about the trap at Linda’s house.
Julie arrives at the same time and assists them in constructing the trap.
The next day, the senior officer ate dinner with his wife.
Meanwhile, a waitress is going to throw out the trash when she hears the rat’s sound.
She isn’t paying attention to him, and the dustbin is littered from the dustbin.
While she is grabbing that, a liquid of some sort begins to fall on her hand.
However, as she looked above, she saw the same rat.
When the waitress sees the rat, she becomes horrified.
Later, when the rat attacks her, the waitress attempts to call another kitchen waiter,
But he is wearing earphones and is unable to hear her.
When the waiter looks behind him, he notices a rat.
The rat ends him before he can do anything. She takes advantage of the situation and flees from the kitchen.
After following her there, the rat arrives and ends the waitress by breaking her neck in front of everyone.
There was also a senior officer present, and the rat attacked everyone.
He ends and preys on a large number of victims one by one.
After grabbing his gun, the senior officer begins shooting him.
When an elderly lady walks between them, his bullet accidentally hits her.
The lady lost the lifes as a result, and the officer shoots the rat.
However, the bullet has no effect on the rat.
The officer is attacked by a rat, which proceeds to eat his stomach.
After some time, the senior officer was ended as well.
Allen, on the other hand, is preparing a chemical at home to end the rat.
Julie goes to his place after leaving them.
Linda begins changing Allen’s bandage after Allen requests her to do so.
Because she is a doctor. We notice the police at Linda’s house at night.
They greet Allen by saying, “It’s great to see you here.”
They request that he watch the news on television, and Allen does so.
A rat-like creature is believed to be roaming the city, according to the reporter.
He’s ended a lot of people, so the government has decided to close the city down.
Allen is asked by the male Sargent if he has any ideas on how to end the rat.
Our senior officer is also ended by the rat, according to the officer.
The senior officer was my friend and Allen says I’ve made a trap to end him.
Allen shows the equipment in the car to the police.
There were numerous fighting weapons around,
And the officer declares that we would end the rat with a gun.
Because I want to seek revenge for the loss of my friend.
Meanwhile, they hear the sound of a rat, prompting them to rush into the house.
Meanwhile, Julie arrives to help them.
Allen hands Julie a baseball and instructs her to be ready right now.
Allen now comes out by himself in order to draw the rat’s attention to him.
After trapping the rat, he could end him.
Linda prevents him from being alone outside the house, but he ignores her and sends her inside.
He asks her to shut it and he starts, the rat enters the house after attacking one by one.
The single rat is dominated by everyone. After holding him, the rat throws the officer.
As a result, he passes out, and the rat now pursues Julie.
After fleeing the rat, Julie finds her way to the upper story room.
She locks the room’s door because of this the rat doesn’t enter the room.
Meanwhile, Allen is listening to the yelling sounds from inside.
As a result, he attempts to enter but is unable to do so due to the room’s lock.
The rat later spots the female Sargent and pursues her.
The Sargent emerges from the home through a window, eluding him.
Meanwhile, the rat continues to pursue her and follows her.
While racing through the lab, the Sargent enters and begins sprinkling acid on the rat.
Meanwhile, we can observe that the acid has no effect on him as well.
The Sargent locks herself in his cage, and the rat starts breaking it down.
Julie, on the other hand, discovers a file in the residence. She gets shocked when she reads that.
The Sargent, on the other hand, begins to grip the knife that has been placed near the cage.
Meanwhile, the cat separates her hand after attacking it.
Meanwhile, Linda arrives and immediately begins shooting the rat.
These bullets have no effect on the rat. After fleeing, Linda immediately exits there.
Julie continues her journey to Allen after receiving the file.
Meanwhile, she notices the mouse in the room eating Sargent’s body.
Julie exits the room and comes to Allen soon.
She later reveals that Linda had done an experiment on the rat, not her husband.
She wanted to treat her mother recover from the experiment.
But she has tested this chemical on the rat and as a result, the rat transferred into a creature.
Linda overhears their talk and Allen confronts her with the truth.
Linda claims I’ve only done this as a result of my mother’s treatment.
Because I wanted to save her in whatever way I could despite my efforts,I was unable to save her.
That’s why I created an antidote so it won’t happen to anyone else as it happened to my mother.
It is revealed that the antidote ends cancer cells in the body.
The antidote is still missing something, and as a result, the effect became reversed.
After a period of decreasing the number of cells, the number of cells begins to increase.
This was the reason for the rat’s increased size.
Linda later asks them inside the house.
Because I’m going to end the rat by myself, I won’t be able to harm anyone else.
Later, an officer attacks Linda and causes her to pass out.
Allen, Jillie, and the officer are asked to leave the house.
He delivers the chemical in gas form into the room where the rat was.
Linda, who has come to end the rat, arrives in the meanwhile.
However, after attacking her, the rat ends her.
Three of them have now escaped the house by escaping the rat.
The chemical causes the rat to grow larger and more dangerous.
They become afraid after witnessing him and begin to flee.
Now that the rat is following Allen and Julie, the officer pulls out his gun and starts shooting him.
The officer is ended and eaten by the rat. The rat now pursues Julie and knocks her down.
Suddenly, the rat begins to writhe in pain.
And when Allen arrives at Julie, he informs her that the rat’s cells have grown as a result of the chemical.
As a result, the rat will get larger, and this happens the same.
The rat grew larger, and we saw that the rat burst and eliminated as a result of the increased cell number.
The rat’s blood splatters all over them, and they act as if everything is great and normal.
However, in the last scene , as they were returning home, they began to hear the sounds of gigantic rats.
This movie ends here.
