It is another morning in Korea, and Chang-Bok together with his mute partner Tae-In go to
town with their truck to sell their daily delivery of eggs.
Afterward, they drive to an abandoned house in the countryside to work on their second
job: they are the clean-up crew for a crime organization.
While they are getting their tools ready to take care of today's body, they are surprised
to discover their boss Yong-Seok is still in the building.
They are not done with the body yet, in fact their victim is still alive, meaning that
the cleaners will have to wait outside while they finish.
Tae-In takes his boss' jacket to hang and can not help looking at himself in the mirror
with it, wondering what would be like to wear such fancy clothes.
Afterward, Tae-In gets into Yong-Seok's car to take an expensive cigarette and use his
fancy lighter, but Chang-Bok quickly drags him out before he can get in trouble.
By the time they have finished their lunch, Yong-Seok is also done with the body, so he
gives the cleaners some cash before leaving.
Chang-Bok and Tae-In wrap and clean the victim, then they bury it on the hill, where Chang-Bok
reminds Tae-In to never forget to pray.
Afterward, Chang-Bok drives Tae-In home, although he leaves him near the road and not exactly
by his house.
Tae-In takes some eggs with him that he gifts an old granny that is always selling things
by the road, then he takes his bicycle which left there earlier and rides it to his very
humble house.
The next day, criminals Jeong-Han and Young-Muk kidnap a special person that Yong-Seok wants
the cleaners to take care of.
However, when the duo arrives at the pick-up point, they are shocked to discover there
is not a body to clean: just a little girl called Choo-Hee.
Chang-Bok calls their boss and confirms this is, indeed, the right job: the girl has been
kidnapped and until the parents accept to pay the ramson, Chang-Bok and Tae-In must
play babysitter.
Chang-Bok lives with too many people and there always are eyes following him everywhere,
so Tae-In will have to be the one Choo-Hee will stay with for the next few days, no matter
how much he dislikes the idea.
As they drive out of there, in order to keep her calm, Chang-Bok tells the girl that they
are friends of her father and that he will pick her up in a few days.
Once they make it to Tae-In's road, he puts Choo-Hee on the bike with him to go home,
but Choo-Hee jumps off and tries to ask the old granny for help.
The woman does not understand she is in danger and tells her to listen to her brother, so
Tae-In drags her back on the bicycle and ties her to himself to stop her from escaping again.
Night has fallen by the time they make it home, and Choo-Hee discovers Tae-In does not
live alone: he has a little sister called Moon-Ju.
Tae-In locks the door, feeds the girls some snacks, then goes to sleep with Moon-Ju clinging
to his back while Choo-Hee tries to stay as far away from them as possible.
The next morning, Tae-In gets a message from Chang-Bok saying he should lock the girl up
and come to work.
Tae-In can not leave the door locked because his sister needs to have access to the bathroom
outside, so he ends up bringing Choo-Hee along.
It turns out today's body is Young-Seok himself, who has been punished for making deals behind
his superiors' backs.
Chang-Bok asks the other gang members if they can pay them the bonus Young-Seok had promised
for the girl, but they do not know anything about it because kidnapping is precisely one
of Young-Seok's unapproved plans.
The duo does the cleaning as usual while Choo-Hee watches, and Tae-In takes the chance to steal
Yong-Seok's fancy suit.
When they finally bury the body, Choo-Hee helps them with the dirt.
Afterward, Chang-Bok and Tae-In visit Jeong-Han and Young-Muk to decide what to do with the
girl now that Yong-Seok is dead.
After discussing many options, including selling her to a trafficker, they agree they will
try to contact the parents and get the ramson for themselves, which will be much bigger
thanks to Yong-Seok being out of the picture.
Jeong-Han explains they need to buy kids stationary and make Choo-Hee write the letter to her
parents, so Tae-In does exactly that.
Once the letter is ready, he takes it back to Young-Muk while the girls stay home using
the new supplies to have fun coloring, and Choo-Hee teaches Moon-Ju not to draw on the
floor.
When Tae-In returns with good food this time, Choo-Hee decides to teach Moon-Ju more manners
while he is outside washing the suit.
The girls proceed to put a table up, fold all the clothes, clean the room, and wait
for Tae-In to return before they start eating - Moon-Ju even begins saying "please" as well.
Tae-In can not believe what he is seeing, but he is glad to see his sister has made
a friend.
Once Tae-In and Moon-Ju go to sleep, Choo-Hee tries to steal the phone from Tae-In's pocket,
but he wakes up before she can pull it out.
To cover up her plan, she pretends she woke him up on purpose so he would take her to
the bathroom outside.
During the following days, Choo-Hee continues to go with Tae-In to his cleaning jobs, helping
with anything she can and not showing signs of minding the blood.
She also teaches Moon-Ju how to do the chores in order to help around the house and even
manages to make Moon-Ju wash her hair and wear clean clothes.
One afternoon, Chang-Bok comes over with a polaroid camera that Choo-Hee must teach them
how to use.
After he takes a sad picture of the girl to send her parents, they prepare another letter,
and Chang-Bok calls Jeong-Han to arrange their next move.
It seems Chang-Bok will have to be the one to pick up the money, but he does not trust
the father to pay up.
So before leaving, he leaves Tae-In the address to the house of the child trafficker - if
tomorrow Chang-Bok does not call Tae-In to confirm he has the money, Tae-In must take
Choo-Hee to that place.
The next day, Chang-Bok goes to town and waits for a man with a blue cap to show up to leave
a bag in an alley.
Once the man leaves, Chang-Bok rushes to grab the bag and leaves as well, but he can not
help feeling everyone is watching him.
Thinking this could be a trap, Chang-Bok begins running and ends up falling down a set of
stairs, hitting his head.
For just a moment, he manages to stand up and walk a little, only to fall again and
die seconds later.
Tae-In keeps calling Chang-Bok to no avail, so he gives Choo-Hee the things she arrived
with and takes her away, ignoring Moon-Ju's cries because she does not want to lose her
new sister.
Choo-Hee is taken to Il-Kyu, a trafficker that is already getting a bunch of kids ready
for sale when Tae-In arrives.
Because Choo-Hee is older than what Jeong-Han had promised, they will be paid five percent
less.
Tae-In leaves as Choo-Hee is forced to drink a suspicious liquid that doesn't taste good
- she looks devastated because she is finally understanding her dad will not come for her.
When Tae-In returns home, he is shocked to find the dried suit waiting for him inside
his room, probably because Choo-Hee hung it there for him to avoid wrinkles.
This causes him to feel incredibly guilty over what he just did, so he jumps on his
bicycle and follows Il-Kyu's van, which is full of children.
Tae-In catches up and throws himself through the window into the vehicle, fighting Il-Kyu
for control of the van.
After exchanging a few hits, Tae-In manages to overpower Il-Kyu and pushes him out of
the van before driving away, only stopping to pick up his bicycle.
Once they are far enough, Tae-In abandons the van with the kids in it in front of a
store and drags Choo-Hee with him, which proves to be difficult because she keeps fighting
back.
On their way back, Choo-Hee keeps throwing up, so as soon as they arrive at the house,
Tae-In looks for some medicine.
Sadly he doesn't have any, causing him to leave for the store to buy some.
This time, he forgets to lock the door, which means Choo-Hee will take the chance to escape.
Moon-Juu does not want her to leave, and Choo-Hee distracts her by pretending to be playing
hide-and-seek.
By the time Tae-In comes back, night has fallen and Cho-Hee is gone, thus he wastes no time
in going after her.
Meanwhile, Cho-Hee manages to reach the road and finds an old man on a bicycle passing
by, so she asks for help.
However, the old man speaks in a weird, creepy way, and when he grabs her wrist, Cho-Hee
gets scared, causing her to run away again as the old man calls the police.
Since they're both running through the tall grass, it doesn't take long for Tae-In and
Cho-Hee to bump into each other, and they return home together.
Back to the old man, he has been found by officer Han-Sol, who listens to his story
about a lost girl and decides to look for her.
Eventually, she makes it to Tae-In's house, and when he hears she is looking for a lost
girl, Tae-In panics and tackles her to the ground.
While Choo-Hee distracts Moon-Ju so she does not see what is going on, Tae-In and Han-Sol
desperately fight until Tae-In pushes her back and hits her head against a rock.
Tae-In gets even more anxious because he never wanted things to end like this, but Choo-Hee
stays calm and grabs a shovel, reminding Tae-In of Chang-Bok's lessons.
With the help of the girls, Tae-In digs a hole and buries Han-Sol, but afterward, his
conscience will not let him sleep.
The next day, Jeong-Han and Young-Muk visit Il-Kyu, whose arm is in a cast after the incident
with Tae-In.
Il-Kyu is furious because all the kids escaped, so he gives the kidnappers directions to reach
the area he had seen Tae-In come from on his bicycle.
A few hours later, Jeong-Han and Young-Muk reach the road and find the old granny, who
gladly tells them where to find Tae-In's home after she hears them say they are his cousins.
Back in the house, Tae-In finds one of Choo-Hee's books and notices the name of her school is
on it, which he takes as a sign to get this over with.
The two of them leave together after Choo-Hee picks up all her things, but sadly she can
not say goodbye to Moon-Ju because she is sleeping.
Sometime after they leave, Jeong-Han and Young-Muk arrive at the house and find Moon-Ju.
Thinking she is Choo-Hee, they convince her to come out by offering candy, saying Tae-In
sent them to pick her up.
They are ready to leave with the girl when suddenly, they notice something weird on the
ground: it is Han-Sol's hand trying to get out because she is still alive.
Jeong-Han and Young-Muk assume Tae-In has gone crazy and overreacted over a witness
so they dig her out, but their mood instantly changes when they notice she is a police officer.
The duo grabs Moon-Ju and tries to leave, but even in her dizzy state, Han-Sol does
her job and grabs Young-Muk's leg, causing the men to decide to leave the girl behind
and get out of there before they get in trouble.
Meanwhile, Tae-In and Choo-Hee take the bus to the city.
When they reach her school, Choo-Hee rushes to reunite with her teacher, who has been
worried sick about her.
Choo-Hee tells her Tae-In was the man that kidnapped her, so the teacher immediately
calls security.
Tae-In hears her and runs away as fast as possible, getting rid of his precious suit
jacket along the way as he thinks of what step to take next.
