Miracle in Cell No. 7 (; lit. "A Gift from Room 7") is a 2013 South Korean comedy-drama film starring Ryu Seung-ryong, Kal So-won and Park Shin-hye. The film is about a mentally challenged man wrongfully imprisoned for murder, who builds friendships with the hardened criminals in his cell, who in return help him see his daughter again by smuggling her into the prison. The movie is based on the real-life story of a man who was tortured and pleaded guilty under duress to the rape and murder of a 9-year-old girl on September 27, 1972 in Chuncheon before being finally exonerated in November 2008. Its early working title was December 23 (). Plot Ye-sung is a lawyer defending her late father for a crime he did not commit. While leaving the prison court after a successful trial, Ye-sung notices a balloon caught on barbed wire and reminisces about the past. Back in 1997, 6-year-old Ye-sung and her father, Yong-go (who is mentally disabled), stare into a store window admiring a Sailor Moon backpack. Yong-gu promises to buy Ye-sung the backpack when he gets paid. However, the police commissioner and his daughter purchased it before Yong-gu. When Yong-gu rushes in to grab the backpack, he is assaulted by the police commissioner and kicked out of the store. After the incident, the two return home without the bag, slightly battered, but in high spirits. The next day, after work, the commissioner’s daughter spots Yong-gu and tries to show him another store selling the same backpack. In an unfortunate accident, the little girl slips running on the market’s icy pavement and a brick drops on her head, killing her. Yong-gu is arrested for rape and murder after his futile attempts at CPR are misconstrued by a female bystander. Yong-gu is sent to prison, where he shares a jail cell (titled "Room 7") with five other inmates, all who initially dislike him for his falsely accused crime and mental disability. One day, Yong-gu saves the life of his cellmate and prison gang leader, So Yang-ho, from being stabbed by a rival prison gang leader. Touched at this, Yang-ho then offers to help Yong-gu in any way he can to return the favor. Yong-gu tells Yang-ho that he wants to see his daughter Ye-sung. The inmates successfully smuggle Ye-sung into the prison when her choir visits the prison for a performance. Ye-sung is introduced
