This movie indeed drives me crazy. I've been crying for almost the whole movie and now my eyes looks like panda's eyes. The story is really touching yet the main leads are potraying their character perfectly. It tells about Lee Yong-gu, a mentally handicapped man with an intelligence of a 6-year-old, which is actually the age of his own daughter Ye-sung who is much smarter than her peers. The two of them lead a happy life on their own while Yong-gu makes a living by working as a parking attendant at a local supermarket. But one day, when the police commissioner’s young daughter dies in a strange accident, Yong-gu who happens to find her is falsely accused and sentenced to death for abduction, sexual assault, and murder of a minor. Ye-sung is sent to a childcare institution and Yong-gu gets imprisoned and assigned to Cell No.7, the harshest cell in a maximum security prison. At first, other inmates in the cell keep their guard against Yong-gu, then realize that there's something wrong with him. Not understanding his own dire situation, Yong-gu only worries about his daughter. One day, he saves his fellow cellmate, an influential figure in the prison, from an attack by his rival. In return for saving his life, Yong-gu is granted a wish: to see his daughter Ye-sung again. The inmates put their heads together to carry out a daring operation and miraculously succeed in sneaking Yesung into Cell No.7 during a religious event. While the father and daughter rejoice, the others realize it was relatively easy getting her in, but impossible getting her out. After a while, Yesung is detected and sent back, but during the time the inmates as well as the prison guards come to realize that Yong-gu was falsely charged. And they all put their heads together to prepare him for his final trial.
What makes this movie great is it shows us a really touching daddy-daughter relationship. Ye Seung still loves his father very much despite his disability. I love how it is not only a pure family movie but they also put a comedy element in it. I didnt realise how many tissues I've used while watching this movie. The child actress, Kal So Won, is just 7 years old but she managed to portray her character perfectly. This movie was a box office despite its low budget. The film exceeded 12 million viewers 46 days after its release. On March 15, 2013, 52 days after its release, ticket sales reached 12.32 million, making it the third highest grossing Korean film of all time. In one side you can laugh like crazy because of the inmates' act and on the other side, you can cry because of the touching moment. Make sure you put a box of tissues close to you while watching.
