Her father works at a local factory and her mother runs a modest neighborhood stationery shop below their home. So-Won is supposed to walk to school with her friend, but her friend ditched her for his group of guy friends. So-Won does not make it to school. Hours later, So-Won's father Dong-Hoon (Sol Kyung-Gu) receives a gut wrenching phone call from the police. So-Won is now hospitalized after being brutally sexually assaulted. Can their family put back the pieces of their once happy home?

An 8-year old girl named So-won is living a blissful life with her parents, Dong-hoon and Mi-hee.

One day, she is late for school. Her school is not that far from home. She decides to walks alone. On the way, her friend Young-seok ditches her for his friends. Moments after, a man approaches her and asks if she could share his umbrella with him (as it is raining and he is all soaked up). She is kidnapped, raped and beaten. Luckily, she survives and manages to call an ambulance.

Dong-hoon and Mi-hee rush to the hospital after being notified. Accrding to a scan, So-won has internal injuries. They go to the emergency room; and they are more than devastated to see her injuries. She gets an emergency surgery afterwards. She will have to wear a colostomy bag for the rest of her life.

Three days later, the police arrives to do an interview with the police. A therapist named Jung-sook informs her parents that she is psychologically unstable just after 3 days. With some help from the therapist, she does the interview. She also identifies her attacker from photos. Afterwards, Jung-sook tries to help the parents with So-won's mental health, however Mi-hee refuses.

Meanwhile, her attacker gets arrested. As the family is moving rooms to a shared room, Dong-hoon gets a call and finds out about the arrest. He runs to the police station in an attempt to see him; however moments later he rushes out as news reporters try to get an interview with him.

Details of the incident ends up on the news; even showing the hospital where So-won is currently staying at. Dong-hoon finds out about this and runs back to the hospital to save his daughter. As he is carrying her upstairs and to a new room; her colostomy bag leaks. After he sets down So-won on the bed; Mi-hee goes to check on her and sees the leaking bag. She runs out and calls for help. She shortly faints afterwards.

The traumatic incident is still fresh in So-won's mind as she starts crying and screaming at her father, telling him to stop. He then finally lets go and realizes what is going on; she is scared of men; including her own father. Nurses go in to help her leaking bag.

Mi-hee is also hospitalized; and it is revealed that she is 5 months pregnant. Dong-hoon is seen sobbing afterwards; likely due to the aftermath of the situation.

Later on, at nighttime, he tries talking to So-won again. However; she is covered up in a blanket from embarrassment; and only being silent. She can't even look at him anymore due to her trauma. He starts trying to find ways to communicate with her daughter.

The next day, after Mi-hee and a few friends try to cheer her up by dressing up in cartoon characters and dancing, He gets the idea of dressing up in her favorite character, Cocomong, to talk to her. At the same time, Mi-hee allows her daughter to get help.

That night, it is revealed that Jung-sook's daughter had a similar experience, however committed suicide. Jung-sook attempted suicide at that same year, causing her to be in a wheelchair.

Dong-hoon dresses up as Cocomong and talking to So-won is a great success. She hugs him and they hug together; not knowing her father is behind the mascot.

So-won starts getting therapy, and soon enough, she starts talking again after having to use a magnetic erase board instead of talking due to the trauma.

Her physical health improves and she is able to go home. On the way back home, she sees the site where the incident happened, and vomits once she gets home. The family then sees positive notes around the front of their house. The house has also been cleaned while they were away.

Her friend Young-seok feels guilty for ditching her the day it happened. He pays a visit to Dong-hoon, and starts crying due to the guilt. He comforts him by giving him candy.

He then visits her daughter's school to inform them about the colostomy bag, and also asks if she can avoid contact with male teachers. So-won is insecure about her colostomy bag, and the crackling noises it makes. Dong-hoon helps her by putting candy in a bag she could use to cover up the colostomy bag.

Soon enough, she figures out that her father is the one behind the mascot. When they returns home, she reveals his face and smiles at him; helping him by wiping off his sweat. She is no longer scared of him.

Time passes on, and Dong-hoon visits her attacker in jail. He does not remember anything, as he was drunk. Dong-hoon gets furious and even goes as far as throwing his chair at the window multiple times out of rage; however the glass between them does not break and an officer puts her attacker back inside his jail cell.

The day of being in court comes. So-won identifies her attacker through photos again, and she reveals that he smelled like alcohol when it happened. He is only sentenced to 12 years in prison, causing outrage. Dong-hoon gets an item and goes behind him in an attempt to hit and kill him; however So-won rushes in time and saves him, begging him to go home while sobbing. He agrees and they go home.

Time goes by, and her baby brother is born. She has to go home early from school sometimes because she still struggles with her mental health. She likes building things (papercrafts) now. The movie ends with her happily playing with her brother; meanwhile holding a paper plane she made for him up in the air.
