Death row convict Jang Jin (Chang Chen) attempts to hasten his death sentence by stabbing himself in the neck with a sharpened toothbrush, only to fail miserably, leaving him temporarily mute. The unfortunate incident reaches the national news, catching the attention of housewife Yeon (Park Ji Ah). On the surface, Yeon's life resembles the ideal picture - a good husband (Ha Jung Woo) a stable livelihood. But beneath that shell lies sadness and torment over her husband's extramarital affairs.
Jang Jin's story hits close to her heart, leading her to a new path, as she dares to leave her usual life to meet the convict in prison. Ironically, it's inside a cold and dark place where all of life's pleasure and privileges have been stripped away that both Yeon and Jang Jin begin a remarkable healing process. But reality remains stern and cold for the condemned as death penetrates through the iron bars, still demanding for his last breath.
