The film begins by showing a single youngster named Fin who has just awoke from his sleep.
He lives with his older brother, Jake, and his brother's girlfriend, Mia, in the same house.
Fin's life wasn't quite as good as the other youngsters'.
Because his father worked abroad and his mother died while he was a child.
Fin spends more time at school everyday and never misses a school.
Instead of studying, he go to school with his pals Whitely and Joel to annoy everyone.
A female teacher, in fact, is asked to dinner with his red-jacketed friend.
Whitely, his red-jacketed classmate, is the most discourteous of this three students.
On the other hand, we are shown a man who has just finished parking his car at the school.
At that time, Fin and his friends worked together to make the man's car scratch.
Even at school, they still had time to carry a knife which is clearly a prohibited object.
Without a second thought, the car that didn't know who it belonged to is slashed with a
bad word.
From their expressions, no one felt guilty at all.
During gym class, Fin with his rude behavior even deliberately did not bring sports attire.
But instead of apologizing, Fin even insults his gym teacher with offensive words.
Likewise with his friends, Fin also very difficult to handle.
Even the gym teacher didn't know what to do anymore.
In the afternoon, Fin is invited by his brother's girlfriend, Mia to go swimming with them.
Mia who is dating Jake already lives in one
house because Mia has a bad relationship with her mother.
The point is, the three of them live without parental control at all.
As a result, their behaviour is unrestricted, and they can act in whatever they want.
The next day at the school a new language teacher, Mr. Gale arrived.
Mr Gale's first day of teaching at the school was not so good.
Worse yet, when he was just explaining about what books to use, Joel immediately make fun
of Mr Gale and yelled at him rudely.
Instead of being well received, Mr Gale was
said to be stinky and ridiculed by his own students.
Eventhough his intention was very good to provide education to his students.
Whitely who was in the class also climbed
into the chair and didn't care about Mr Gale's shouting.
Immediately, Joel walked straight to front of the class and put the gum in Mr Gale's hair.
If it's like this, the teacher, whatever he or she is, will undoubtedly have anger.
Whether it's a girl student or a boy student, one class is equally insolent.
Mr Gale was angry and mumbled while controlling his feelings.
Whitely, on the other hand, didn't feel sorry for Mr Gale and challenged him to a fight.
Whitely was not happy with Mr Gale's gaze that was fixed on him but Mr Gale ignored
him and continued to explain to his students what they were going to study.
Fin, Whitely, and Joel with a bad plans went to a shop after school to buy cigarettes.
Fin, on the other hand, grabbed one bottle of drink and was caught by the shop owner.
The three of them rushed to an empty field, far away from the shop owner's chase.
They being hated so much that the small children even made fun of the three of them.
Fin, Whitely and Joel's close relationship makes them inseparable both inside and outside
school.
Three of them are not properly monitored by their parents and act irresponsibly but the
difference is that Joel still has hope to get better.
Joel said that his father would bring him to join the military school, whereas Whitely
and Fin don't know what they are going to do after they graduate.
That's if they can graduate with such a brutal nature.
At night, Fin just arrived at the house and saw Jake seducing Mia to make love.
Seeing that, Fin didn't go up to the room and went downstairs again.
In fact, when Fin is at home, he is a pretty quiet man.
He doesn't even talk to his brother or Mia very much.
Fin will have breakfast before going to school in the morning.
He had his 16th birthday today, and Mia wished to him immediately about it.
Jake, on the other hand, not giving any wishes.
Jake even tells Fin to get his own place and stop living with them.
Mia felt remorse for Jake's statements at this point, and Fin quickly responded that
this house belonged to their father.
He is upset with his own brother, who already act good since he pays the house's rent.
Fin spent the entire day with Whitely, from morning to late.
To fill their boredom, they openly destroy bicycles belonging to residents.
It's really the definition of an immoral person that causes terrible things to innocent people.
When they were finished, they walked as far as they could along the highway.
But suddenly, their heads were hit from behind by someone.
At that time they were kidnapped and taken away by car.
Then, Fin and Whitely who were already bleeding were immediately dragged into a room.
They were chained and padlocked so they couldn't move an inch.
That guy also deliberately drilled the table to make holes so that fin and whitely hands
could be tied using a thin rope.
This method is the most effective way to make them both can’t move.
That guy, on the other hand, had also set up a blackboard in the room.
Then, Fin pees in his pants when he sees Whitely unconscious.
Turns out, the mysterious person actually is their new teacher, Mr Gale.
Without saying much, Mr Gale explains the lesson material for the day.
Because today the material is nouns, then Mr. Gale gives an example for each object
that is there.
Like hammers, nails and nail gun.
And not long after, Mr Gale told Fin to look up every meaning of the word he mentioned
in the dictionary.
Every chance, Fin only has 10 seconds and if Fin can't find the word in the dictionary,
then his hand will be impaled with nails.
This time Fin was asked to find the meaning of the 'inspiration' word.
With panic and fear, Fin kept looking and luckily he managed to find the word.
It doesn't stop there, if Fin has found the word in the dictionary, he must read the meaning
and remember it in his mind.
Mr Gale also said that for every explanation and question he gave,
a test will be held at the end of the meeting.
Fin is really forced every time to quickly open the dictionary.
Mr Gale gives each of these orders suddenly and unexpectedly by Fin.
Mr. Gale believes that in learning activities, motivation is needed.
Therefore, he has his own way to motivate his students who are too disrespectful.
Then Fin tells Mr. Gale that Whitely has been dying and unconscious for a long time.
However, Mr Gale instead taped Fin's mouth and nailed his hand with nails.
He said that Fin did not understand at all the essence of this class.
Mr. Gale wants his students to feel what is called pain because in life, nothing goes
without pain.
Well.
It is possible that Mr. Gale's way of learning has already implemented the 2100 curriculum.
After that, he resumed learning activities and explained everything on the blackboard.
If there is a word that is complicated, he tells Fin to open a dictionary and look it
up.
But amazingly, with 10 seconds, Fin always managed to find the words he asked.
In this condition, Fin was forced even though he didn't want to but he have to remember
all the explanations.
In Mr Gale's classroom, there is a 30 second break for drinking a glass of water.
Fin was immediately given a drink by Mr Gale and so did Whitely who was unconscious.
The longer this class lasts, the more sadistic Mr. Gale is as a psychopath teacher.
This time the challenge becomes more complicated and Fin is told to find each word in only
7 seconds.
If he could not answer, then he would be impaled with a nail gun.
But sure enough, Fin couldn't answer and his hand was immediately shot with a nail gun.
Mr Gale's emotional state only gets worse when Whitely has been unconscious for a long
time.
As a result of Whitely's actions before, Mr. Gale also deliberately impales Whitely's hand
with a nail gun.
Coupled with a second nail that was hammered manually with a hammer.
The atmosphere turned even more chaotic and Mr Gale was not in the mood to educate the
two of them.
On the other hand, Mia, who is with Jake, is concerned about why Fin isn't returning
home.
He attempted to contact Fin, but his phone was not active.
Fin’s brother , on the other hand, is completely unconcerned, which contrasts with Mia's caring
personality.
Mia also sends a message to Fin in the hope that it will be read.
But Jake saw it and immediately became jealous of Mia.
Jake says what's so important about Fin that you're looking for him.
In the end, Jake uttered harsh words and made Mia leave the house.
Mia is also threatened not to return to the house again and go as far away from the house
as Fin.
Mia who walked far from Jake's house met Joel who was waiting for his father to pick him
up.
Joel was very lucky because today he didn't play with Fin and Whitely because he was invited
by his father to join military school.
At that time Mia asked Joel to call Fin but still he didn't pick up at all.
Yeah.
From here we can see that even a friend can only be with us when we are happy, but when
we are in a difficult condition, very few friends are willing to help us.
Then, Mia walks in the middle of the night alone and hopes to meet Fin.
After a while, she saw a parked car with scuff marks on the back of the body but suddenly
from a distance Mia was chased by a man and she ran away as best he could.
Unfortunately, she was caught by that man. and it was clear that the man was Mr Gale.
Then, Mia was brought into the room and held together with the two of them.
Mr Gale says he already knew someone would be looking for Fin or Whitely and sure enough,
the long-awaited prey had arrived by accident.
This time the number of students from Mr. Gale was 3 people.
Learning activities are not getting more exciting but even more sadistic.
At that moment Mr. Gale told Whitely to read a meaning from the dictionary but Whitely
instead banged Mr. Gale's head against his own head.
It didn't take long for Mr Gale to take a nail gun and shoot it into Whitely's neck.
Well.
From this it was clear that Whitely had to die with the nail pierced through his neck.
In such hysterical conditions, Mr Gale said that he was able to become like this because
the demands of his parents who forced him to study too much.
Therefore, if there are students who are lazy, he will provide education in such a brutal
way.
Then Fin has entered the exam session and he has to answer all the questions that are
given quickly.
This is the last session which is certainly really stressful for Fin and Mia.
Before it begins, Mr. Gale tells her that Mia will be the victim if Fin incorrectly
answers any of his questions.
For 1 question, Mia's head will be pricked with a nail.
Amazingly, question after question given by Mr. Gale was successfully answered by Fin.
At that time, Mr. Gale was proud that the method he applied succeeded in making Fin
a genius.
At the same time, Mia secretly wanted to take the nail that was on Whitely's neck.
When it was taken, Mia immediately stuck the nail right into Mr. Gale's neck.
She also let go of the rope in Fin's hand, but unfortunately Mia's head was hit with
a hammer from behind.
With so little time, Fin pulled his hand away from the nail.
Fin also managed to pick up the fallen knife and immediately cut both thumbs in Mr. Gale's
hand.
With the thumbs loose, he would have a hard time taking anything with his own hands.
The unwise thing is, Fin allowed Mr Gale to stand up under the pretext of taking the keys
so they could escape from here.
But Mr Gale lied and he just stepped on Fin many times.
Luckily, Mia had regained consciousness and she immediately hit Mr Gale with a hammer.
Time and time again she hit Mr Gale with so much emotion that his head was crushed.
At that time, Mia also managed to kill Mr. Gale and she found the key to escape from
the house.
They walked alone down the street in the middle of the night to return home.
The cool thing is, when they got home they both kicked Jake out of the house.
How not, Jake can only be steady and not help at all.
In the end, they both spent time watching TV and the movie ended.
