Lee Yong-go is a mentally impaired father with the intellect of a six-year-old, who lives in a run-down house along with his daughter of the same age, Ye-sung. One day, he gets into a physical altercation with the police commissioner, who has just purchased the last Sailor Moon backpack for his daughter, a gift Yong-go was saving up to buy for Ye-sung. Soon after, the police commissioner’s daughter dies in a freak accident, in which she slips on ice and suffers a fatal blow to the back of her head while she is taking Yong-go to another store that sells the same backpack. When he tries to resuscitate her, a woman witnesses him and mistakes him to be molesting her. Yong-go is falsely accused of the abduction, murder, and rape of a minor. The police quickly took advantage of his disability and forced him to admit committing the crimes, while ignoring exonerating evidence. Yong-go, who is sentenced to death, is imprisoned and assigned to Cell No. 7, the harshest cell in a maximum security prison.
At first, the other men in the cell, led by gang leader So Yang-ho, do not take kindly to Yong-go after reading in his file that he murdered and molested a child, but when Yong-go saves Yang-ho from being fatally stabbed by a rival gang leader, Yang-ho repays the favor by smuggling Ye-sung into Cell No. 7. Over time, they come to believe in his innocence, and make it their goal to help reverse the verdict at Yong-go’s retrial.
